delivered the opinion of the Court.
Family Services Specialist trainee Tammy Herrmann was charged by her employer, the Division of Youth and Family Services (DYFS), with conduct unbecoming a public employee based on her actions during an investigation into an allegation of child abuse. DYFS sought to terminate her employment. Following a hearing before an administrative law judge (ALJ) in which the charge and penalty were sustained, the Merit System Board (MSB) affirmed Herrmann’s dismissal. On appeal, howev

I.
Only the quantum of punishment, and not the sufficiency of the evidence in support of the disciplinary charge, is in issue in this appeal. Therefore, we recite the background evidence to the charge as credited by the ALJ and affirmed by the MSB.
DYFS hired Tammy Herrmann in February 2001 as a Family Services Specialist trainee. In August 2001, when she was no longer in her probationary period, she was assigned to interview the M. family regarding an allegation of child abuse.
Mr. and Mrs. M. have six adopted children, four of whom were under the age of eighteen at the time that Herrmann was assigned to look into the abuse referral. Mr. and Mrs. M. also were foster parents to a medically fragile infant, Q.T., which brought the family in regular contact with DYFS. The referral to which Herrmann was assigned concerned the family’s sixth and youngest adopted child, J.M. At the time, J.M., a special needs child, was five-and-a-half-years old. Earlier in August 2001, J.M. started a small fire in family’s basement. Mrs. M. discovered the fire, extinguished it before any substantial damage resulted, and immediately telephoned her husband to come home from work, which *23 he did. That afternoon, Mr. M. took J.M. to the local fire marshal for a fire safety lecture. Although the DYFS investigation to which Herrmann was assigned included inquiry into that fire incident, the referral came about as a result of an unrelated incident.
D.M. is a six-year-old, special needs girl who also was adopted by Mr. and Mrs. M. D.M. overheard Mr. and Mrs. M. having an angry exchange with J.M. about the fire and told her summer camp counselors about it. She also told them that her father tied up J.M. 1 The manner in which D.M. described those events led to the referral to DYFS.
On August 6, 2001, Herrmann went to the M. home to meet with the family. According to Mrs. M., Herrmann interviewed her for forty-five minutes before stating the purpose of her visit. Once she informed Mrs. M. that there had been an allegation of abuse and that she intended to interview the children individually, Mrs. M. offered her bedroom, which was air-conditioned, as a comfortable place for conducting the interviews. Mrs. M. showed her the room, specifically drawing Herrmann’s attention to the presence, in the closet, of oxygen equipment used to treat D.M.’s asthma and Q.T.’s medical conditions. Herrmann talked with each of the four children in the bedroom over the next several hours. Only when Herrmann was about to leave did J.M. finally admit that he started the fire.
Herrmann’s interactions with J.M. lie at the heart of this disciplinary matter. The ALJ heard divergent accounts about it from the witnesses. In the end, the ALJ credited DYFS’s witnesses as credible, consistent, and believable. Conversely, he did not find Herrmann’s explanation to be credible or believable.
According to Herrmann, the exchange with J.M. took place in the hallway outside the parents’ bedroom. Mrs. M. testified that she believed that J.M. and Herrmann spoke in the bedroom that *24 contained the oxygen tanks. In respect of the substance of the exchange, Herrmann said that she asked the child what kind of lighter he used to start the fire. When he did not answer, she knelt in front of him, extracted a cigarette lighter from her purse, and held it in front of his face. She testified as follows in respect of the incident.
So I said, “Well, did you light it like” — and I went to show the difference between a ball and a lighter or a click-it.
Honestly, do I know if I meant to light it at that point? I don’t know. But it lit. Okay? It definitely lit. And when he saw it he went to grab at it. He — you could tell he liked it. Even though I had been holding it a second prior, until it was lit he wasn’t, you know, that into it.
In her notes documenting the contact with the family, Herrmann did not record waving the lighter near J.M.’s face, nor did she immediately tell her supervisor about it. Herrmann did report to Sheryl Stafford-Curl, her supervisor, that the children should be removed from the home. Ms. Stafford-Curl testified to being skeptical about that recommendation because Herrmann tended to advocate for removal frequently. Ms. Stafford-Curl asked Herrmann to collect more information, to have a fire assessment test of J.M. performed by DYFS’s independent contractor for that service, and to have the M. family sign a case management plan that restricted Mr. M.’s discipline of the children.
Accordingly, Herrmann returned to the M. home with another case worker, Elizabeth Walters. During that meeting, Herrmann told Mr. and Mrs. M. about waving the lit cigarette lighter in front of J.M.’s face and informed them that J.M.’s “fascination” with the lighter indicated that he may have a propensity to start fires. When J.M.’s parents expressed alarm that the lighter could have ignited the oxygen tanks, Herrmann, in an apparent attempt to allay their concerns, informed them that she was familiar with oxygen tanks from her prior work as a pharmacy assistant. She also chastised the parents for not keeping oxygen notification magnets on the refrigerator.
Mrs. M. testified that she was left speechless when she heard about Herrmann’s dangerous action of having an open flame in *25 close proximity to oxygen equipment. However, although she was upset, Mrs. M. did not protest at the time because Herrmann was threatening to take her children away. 2 Mr. and Mrs. M. ultimately signed the case management plan that Herrmann had presented to them, but because they were distressed with DYFS’s actions, they hired an attorney to challenge the plan. On the day that a hearing concerning the M. family’s plan was scheduled to take place in Superior Court, a deputy attorney general (DAG) representing DYFS, and Herrmann’s supervisor, Ms. Stafford-Curl, learned for the first time that Herrmann had waved a lit cigarette lighter in front of J.M.’s face. The newly revealed information was problematic to each, as they explained in their testimony.
Stafford-Curl testified that she was concerned because DYFS workers are not qualified by training or experience to conduct assessments of a child’s propensity to start fires. She explained that DYFS standards require such tests to be performed by the qualified, independent contractor DYFS engaged specifically for that purpose. She also stated that she believed Herrmann’s conduct, in attempting to perform an assessment of J.M. using a lit cigarette lighter, was inappropriate and dangerous due to the proximity of oxygen tanks.
The DAG set forth a different perspective, one that reflected the position of a litigator confronted with new information from her prospective witness. She expressed the view that Herrmann exhibited bad judgment by holding a lighter in front of the child’s face, even if the presence of oxygen tanks were not considered to be a factor adding to the dangerousness of the action. That breach of judgment by the on-site ease investigator tainted her ability to be a credible witness for DYFS in the agency’s protective services ease. The DAG concluded that she could not allow *26 Herrmann to testify before the Superior Court in the M. family’s hearing. She was concerned that by revealing the worker’s inappropriate conduct to a Family Part judge, Herrmann’s credibility as well as the credibility of DYFS workers generally would be threatened, the judge’s overall opinion of DYFS’s investigatory skills could be tainted, and the State’s ability to obtain relief for other children might be undermined. Ultimately, the parties settled their dispute about the family’s case management plan and a consent order was executed.
As a result of the cigarette lighter incident, Herrmann was served with a Preliminary Notice and then a Final Notice of Disciplinary Action seeking her termination for conduct unbecoming a public employee, pursuant to N.J.AC. 4A:2-2.3(a)(6). She appealed her removal and requested a hearing before the Office of Administrative Law.
Pursuant to N.J.SA 52:14B-10(c), an ALJ conducted a hearing and rendered an Initial Decision setting forth his recommended findings of fact and conclusions of law that determined that Herrmann had engaged in conduct unbecoming a public employee. The ALJ discounted the importance of resolving the dispute over the location of the lighter incident, finding it to be immaterial because “the fact that respondent did it at all places in serious doubt her judgment and her ability to properly perform her assigned duties.” He found that Herrmann’s actions were dangerous and, further, concluded that the Division had proven that Herrmann’s actions undermined the public trust in and credibility of DYFS.
Although noting that principles of progressive discipline can apply in respect of the determination of the disciplinary penalty, the ALJ concluded that Herrmann’s act of waving a lit lighter near a five-year-old child’s face was so egregious that, notwithstanding the lack of a prior history of infractions by this relatively new employee of DYFS, the appointing authority’s determination to remove her from her position was appropriate. Accordingly, the ALJ’s Initial Decision recommended that DYFS’s termination *27 of Herrmann be upheld. The MSB accepted and adopted the proposed findings and conclusions set forth in the ALJ’s Initial Decision.
On Herrmann’s appeal to the Appellate Division, the panel affirmed the MSB conclusion that Herrmann had committed conduct unbecoming a public employee, but vacated Herrmann’s removal from her position.

Reduced to its essence, the issue in this appeal is whether the Appellate Division exceeded the proper scope of its review when it reversed the penalty imposed by the MSB. We start then by acknowledging the well-recognized principles of judicial review of administrative agency actions. The scope of that review is limited.
See In re Carter,
191
N.J.
474, 482,
(1) whether the agency’s action violates express or implied legislative policies, that is, did the agency follow the law; (2) whether the record contains substantial evidence to support the findings on which the agency based its action; and (3) whether in applying the legislative policies to the facts, the agency clearly erred in reaching a conclusion that could not reasonably have been made on a showing of the relevant factors.
[Mazza v. Bd. of Trs., 143 N.J. 22, 25,667 A.2d 1052 (1995) (citing Campbell, supra, 39 N.J. at 562,189 A.2d 712 ).]
When an agency’s decision meets those criteria, then a court owes substantial deference to the agency’s expertise and superior knowledge of a particular field.
See In re License Issued to Zahl,
186
N.J.
341, 353,
That deferential standard applies to the review of disciplinary sanctions as well.
See Knoble v. Waterfront Comm’n of N.Y. Harbor,
67
N.J.
427, 431-32,
With those principles as our guide, we turn to this matter to review whether the Appellate Division erred when it reversed the MSB’s penalty because the panel believed that progressive discipline principles required consideration of a sanction less than termination. That question requires us to examine the principle of progressive discipline and whether it requires the imposition of a lesser, more incremental penalty for this unbecoming conduct charge.

Recently, in
In re Carter, supra,

N.J.

*30 While a single instance may not be sufficient, numerous occurrences over a reasonably short space of time, even though sporadic, may evidence an attitude of indifference amounting to neglect of duty. Such conduct is particularly serious on the part of employees whose job is to protect the public safety and where [they] serve precise shifts to afford continuous protection.
[Id. at 522,186 A.2d 97 .]
We further explained what was meant by a public employee’s “past record” or “record of service:”
We believe that ... the terms should be held to encompass an employee’s reasonably recent history of promotions, commendations and the like on the one hand and, on the other, formally adjudicated disciplinary actions as well as instances of misconduct informally adjudicated, so to speak, by having been previously called to the attention of and admitted by the employee.

N.J.

Since
Bock,
the concept of progressive discipline has been utilized in two ways when determining the appropriate penalty for present misconduct. First, principles of progressive discipline can support the imposition of a more severe penalty for a public employee who engages in habitual misconduct.
See, e.g., In re Hall,
335
N.J.Super.
45, 46, 51,
In a classic example of such use of progressive discipline, the Appellate Division cited to an employee’s history of escalating penalties when it affirmed the MSB’s termination of a police officer in
In re Morrison, supra,
216
N.J.Super.
at 147, 160-61,
In another similar example of the use of past discipline to ratchet-up a penalty for a present offense, the Appellate Division in
State-Operated School District v. Gaines,
309
N.J.Super.
327, 333,
In reversing, the Appellate Division stated that the MSB’s decision to reduce removal to a six-month suspension was clearly mistaken on that record and “was so plainly unwarranted that the interests of justice demand intervention and correction.”
Id.
at 332,
The second use to which the principle of progressive discipline has been put is to mitigate the penalty for a current offense. It is in that sense that the MSB cites the principle of progressive
*33
discipline when it downgrades a penalty for an employee who has a substantial record of employment that is largely or totally unblemished by significant disciplinary infractions.
See, e.g., In re Saniuk,
B.
Although progressive discipline is a recognized and accepted principle that has currency in the MSB’s sensitive task of meting out an appropriate penalty to classified employees in the public sector, that is not to say that incremental discipline is a principle that must be applied in every disciplinary setting. To the contrary, judicial decisions have recognized that progressive discipline is not a necessary consideration when reviewing an agency head’s choice of penalty when the misconduct is severe, when it is unbecoming to the employee’s position or renders the employee unsuitable for continuation in the position, or when application of the principle would be contrary to the public interest.
Thus, progressive discipline has been bypassed when an employee engages in severe misconduct, especially when the employee’s position involves public safety and the misconduct causes risk of harm to persons or property.
See, e.g., Henry v. Rahway State Prison,
81
N.J.
571, 580,
Our appellate courts also have upheld dismissal of employees, without regard to whether the employees have had substantial past disciplinary records, for engaging in conduct that is unbecoming to the position. For example, in
Division of State Police v. Jiras,
the Appellate Division affirmed a State Trooper’s dismissal for an unprovoked assault on a prisoner. 305
N.J.Super.
476, 478, 482,
[i]n the face of these considerations, it is not fitting that we should substitute our judgment for the Superintendent’s policy determination that so basic a breach of performance standards and of duty or discipline as occurred here calls for termination in the absence of special circumstances, explanation or excuse amply demonstrated by the person charged. The record supports the Superintendent’s conclusion that no such showing was adequately made here, as well as his implicit determination that Jiras’s conduct in the acknowledged incident bore very basically on his capacity to function as a State [Tlrooper.
[Id. at 481-82,702 A.2d 1298 .]
The court concluded by emphasizing that, “[a]s a general rule, in reviewing administrative agency decisions, we accord substantial
*35
deference to an agency head’s choice of remedy or sanction, seeing it as a matter of broad discretion, ... especially where considerations of public policy are implicated.”
Id.
at 482,
For similar reasons, the Appellate Division affirmed the dismissal of a police officer for infractions that went to the heart of the officer’s ability to be trusted to function appropriately in his position.
Cosme v. E. Newark Twp. Comm.,
304
N.J.Super.
191, 206,
Finally, the Appellate Division also has found notions of progressive discipline inapplicable when disciplinary charges against a public employee have demonstrated lack of competence or unfitness for a position.
See Klusaritz v. Cape May County,
387
N.J.Super.
305, 316, 318,
C.
As the aforementioned cases reflect, progressive discipline is a worthy principle but it is not subject to universal application when determining a disciplined employee’s quantum of discipline. This is an instance when the MSB did not apply progressive discipline. As a matter of course, we accord substantial deference to the MSB’s choice of sanction. That choice is made weightier when, as in this instance, it is the penalty imposed by the appointing authority and affirmed by the ALJ. Moreover, we cannot say that the MSB’s penalty is so wide of the mark as to justify this Court’s substitution of its judgment.
This ease implicates the public interest in that it reflects the standards of judgment, as well as performance, that DYFS expects of its workers who are sent out into the field to interact with children and families, often in crisis.

See N.J.A.C.
10:129— 2.1 to -2.10 (entrusting workers to obtain and document evidence pertaining to allegations of abuse by means of interviews, safety assessments, medical assessments, and observations, and requiring workers to make decisions as to whether allegations of abuse are founded and whether actions should be referred to law enforcement);

The MSB is the entity charged with keeping State-government-wide standards of employee performance relatively consistent in disciplinary matters.
Ibid.
The MSB agreed with DYFS and affirmed that Herrmann’s conduct constituted just cause for her removal. That judgment reflects sensitivity to the public policy concerns faced by DYFS in the difficult job that it is expected to perform. The face of DYFS — to the public and others who measure its performance
5
— is that of the case workers DYFS
*38
sends out on its behalf.
See generally State v. P.Z.,
152
N.J.
86, 97,
The MSB agreed that Herrmann’s conduct, as proven at the hearing, divested her of the trust necessary for her position and that progressive discipline would not be appropriate in this matter. That choice was the MSB’s to make and it sided with DYFS’s desire to remove Herrmann from employment as a Family Services Specialist. We will not interfere with that determination, regardless of whether we, in the first instance, would have reached the same conclusion.
In conclusion, the MSB decision recognized legitimate public policy reasons for not insisting that DYFS retain an employee who, in so short a time, lost the trust of her employer. The *39 Appellate Division impermissibly imposed its own judgment as to the proper penalty in this matter when the MSB’s penalty could not be said to be either illegal or unreasonable, let alone “shocking” any sense of fairness. Therefore, we hold that the Appellate Division’s reversal of Herrmann’s removal was in error.
IV.
We reverse the Appellate Division judgment in respect of the penalty to be imposed and reinstate the MSB’s penalty removing Herrmann from her position.
For reversal and reinstatement — Chief Justice ZAZZALI and Justices LONG, LAVECCHIA, ALBIN, WALLACE and RIVERA-SOTO — 6.
Opposed — None.
Notes
The investigation revealed that Mr. M. had tied J.M.’s seatbelt after J.M. had released himself from the restraints while Mr. M. was driving.
During the course of Herrmann's ongoing investigation of the referral, Q.T. was removed from Mr. and Mrs. M.’s foster home. According to the record, Herrmann was involved in that removal, having informed DYFS foster care workers that Q.T. was in immediate danger while in the M. home.

To the extent that it has been argued that progressive discipline can be circumvented in the public interest only when police officers, correctional officers, and other public safety positions are involved, we disagree. The public interest can require the bypassing of progressive discipline based on misconduct in other positions that call for discretion and judgment by public servants who exercise substantial authority over members of the public, such as DYFS workers.
It is a matter of public record that DYFS has been sued and is subject to federal court monitoring in respect of its service to the children it is responsible to protect and serve.
See Charlie H. v. Whitman,
As a result of that litigation, the Legislature enacted NJ.S.A. 9:3A-2, creating the Department of Children and Families "to facilitate aggressive reform of the child welfare system and ensure that the reform effort is successful.” N.J.S.A. 9:3A-2(a). Also, pursuant to settlement agreements entered into by the parties, the State has committed itself to protecting children from harm, ensuring that the child welfare system is held accountable to the public, and providing the child welfare system with "the infrastructure, resources, and policies needed to serve the best interests of the children in its care." Charlie H. v. Corzine, Modified Settlement Agreement, No. 99-3678, at 2 — 4 (July 18, 2006), available at http://www.state.nj.us/dci/home/Modified_Settlement_AgreementL.7_17_06.pdf. Monitoring of the State's compliance with those agreements continues to date.
Indeed, the information gathered in a worker’s investigation must be submitted to the court in support of an action for parental termination or guardianship.
See N.J.S.A.
30:4C-16. Such reports containing a worker's first-hand knowledge of the case are treated by the courts as ”supply[ing] a reasonably high degree of reliability as to the accuracy of the facts contained therein.”
