On December 12,1996, plaintiff Michelle Palanque sought medical treatment from defendant Dr. Margaret Lambert-Woolley because plaintiff was experiencing mennorhagia, a heavy menstrual bleeding. Defendant ordered a BhCG test to determine whether plaintiff was pregnant, a possible cause of her condition, but misread the test results and determined that plaintiff was pregnant when she was not. After a subsequent ultrasound test did not confirm plaintiffs pregnancy, defendant ordered another BhCG test that, again, confirmed plaintiff was not pregnant. Yet defendant misread the results again, and this time mis-diagnosed an ectopic pregnancy. 1 She recommended surgery and plaintiff *401 underwent both a dilation and curettage procedure and a laparoscopy. 2 Those procedures revealed that plaintiff was not pregnant.
Plaintiff retained an attorney to investigate whether she had an actionable malpractice claim against defendant. The attorney obtained plaintiffs medical records and discovered that defendant had read the BhCG test results as 1145 and 1421, numbers that were actually the specimen identification numbers оn the laboratory report. The records were submitted for evaluation to Dr. Albert G. Thomas who confirmed that defendant had read the identification numbers incorrectly as the test results. Dr. Thomas issued a report, dated January 23, 1998, stating that defendant Lambert-Woolley had deviated from the standard of care and concluding that “the misreading as positive of the pregnancy tests [led] to the incorrect diagnosis of ectopic pregnancy” and “[t]his deviation led to the performance of surgery which was not needed.” In October 1998, after plaintiff had filed a complaint and after the time for filing an affidavit of merit had passed, defendant admitted in response to requests for admissions that the BhCG test results were “now known” to be less than 5.0 MIU/ML, but that her earlier “understanding was that the ... reading was 1145 [and 1421] MIU/ML.” Defendant also admitted that she “believed the lab reports were consistent with ectopic pregnancy or moler pregnancy.”
On November 2, 1998, defendant moved to dismiss plaintiffs complaint with prejudice for failure to file an affidavit of merit. In response, Dr. Thomas affirmed his January 1998 report, a jurat was added, and the affidavit, dated November 17,1998, was served on defendant before the court heard arguments on the motion to dismiss. The court dismissed plaintiffs complaint with prejudice *402 nonetheless because her affidavit of merit had not been filed within 120 days of defendant’s answer.
The Appellate Division affirmed, denying plaintiffs claims that extraordinary circumstances prevented her from filing an affidavit of merit and, in the alternative, that she was not required to file an affidavit of merit under an exception to the statute for common knowledge cases, that is, cases in which malpractice can be determined without the aid of expert testimony.
Palanque v. Lambert-Woolley,

158, 162, 164,
On the issue whether an affidavit is required in a common knowledge malpractice case, the Appellate Division “assum[ed], without deciding” that a malpractice case in which the jury can determine negligence without the aid of expert testimony does not require an affidavit of merit.

Before this Court, plaintiff argues that the Appellate Division erred when it denied her claim of extraordinary circumstances. *403 She contends that she substantially complied with the statute by obtaining an expert report prior to the commencement of litigation. By seeking early review by an expert she ensured that her claim had merit and fulfilled the legislative intent underlying the statute, the curtailment of frivolous litigation. Plaintiff argues in the alternative that this is a common knowledge ease and therefore does not require an affidavit of merit.
Defendant maintains that the Appellate Division correctly decided that plaintiffs case does not meet either the extraordinary circumstances standard or the common knowledge exception, if оne exists. Defendant reasons that the Legislature deliberately chose not to include a common knowledge exception because the nature of the claim might not become known until well beyond sixty or 120 days after a defendant’s answer. If common knowledge could be asserted after thе time for filing an affidavit had passed, the purpose of the statute — to eliminate frivolous litigation early — could be circumvented.
We now reverse. Although we agree with the Appellate Division that plaintiffs claims of extraordinary circumstances and substantial compliance should be denied, we disagree with the panel’s determination that plaintiff cannot proceed with her case under a common knowledge theory generally described today in Hubbard, supra, 168 N.J. at 389, 774 A. 2d 495.

The Affidavit of Merit Statute provides:
In any action for damages for personal injuries, wrongful death or property damage resulting from an alleged act of malprаctice or negligence by a licensed person in his profession or occupation, the plaintiff shall, within 60 days following the date of filing of the answer to the complaint by the defendant, provide each defendant with an affidavit of an appropriate licensed person that therе exists a reasonable probability'that the care, skill or knowledge exercised or exhibited in the treatment, practice or work that is the subject of the complaint, fell outside acceptable professional or occupational standards or treatment practicеs. The court may grant no more than one additional period, not to exceed 60 days, to file the affidavit pursuant to this section, upon a finding of good cause.
*404 [N.J.S.A. 2A:53A-27.]
The statute was enacted as part of a tort reform package designed to “strike[ ] a fair balance between presеrving a person’s right to sue and controlling nuisance suits.” Office of the Governor, News Release 1 (June 29, 1995). In professional malpractice actions plaintiffs are required to provide an affidavit from an appropriate licensed professional attesting to the merit of plaintiffs’ claims. That requirement was intended by the Legislature to curtail frivolous litigation without preventing access to the courts for meritorious claims. Peter Verniero, Chief Counsel to the Governor, Report to the Governor on the Subject of Tort Reform (Sept. 13,1994).
A plaintiff must file an affidavit of merit within sixty days of a defendant’s answer, but may file aftеr sixty days and up to 120 days of the answer for good cause shown.

First, we briefly address plaintiffs claim that she has demonstrated extraordinary circumstances and should be allowed to file an affidavit of merit out-of-time. Plaintiff contends that because she obtained an expert prior to filing suit, and provided an affidavit within the time frame of the applicable statute of limitations, she has met the extraordinary circumstances standard. Plaintiffs attorney has represented to the Court that the failure to file an affidavit was the result of simple inadvertence. In
Bums,
we found it unnecessary to discuss whether attorney inadvertence constituted extraordinary circumstances. However, the Appellаte Division in that case considered the issue and concluded that
*405
“ ‘carelessness, lack of circumspection, or lack of diligence on the part of counsel are not extraordinary circumstances which will excuse missing a filing deadline.’”

Nor has plaintiff substantially complied with the statute. The doctrine of substantial compliance is used by courts to “avoid technical defeats of valid claims,”
Zamel v. Port of New York Auth.,
56
N.J.
1, 6,
In both Galik, supra, and Fink, supra, the plaintiffs took a series of steps that notified the defendants about the merits of the malpractice claims filed against them. Here, no such action wаs taken. Plaintiff obtained an expert report but did not provide the report or an affidavit to defendant. The action taken by plaintiff falls short of meeting the elements of substantial compliance. We *406 find, therefore, that plaintiff has neither presented a sustainable claim of extraordinary circumstances, nor substantially complied with the statute. Disposition of this case therefore rests on whether plaintiff can rely on a common knowledge exception to the Affidavit of Merit Statute.

In
Hubbard, swpra,
decided today, we held that a plaintiff is not required to file an affidavit of merit in a common knоwledge malpractice case, a case in which “ ‘jurors’ common knowledge as lay persons is sufficient to enable them, using ordinary understanding and experience, to determine a defendant’s negligence without the benefit of the specialized knowledge of experts.’ ” 168

Here, plaintiff has asserted that she will rely on the common knowledge doctrine. She points out that medical records she *407 obtained priоr to filing suit reveal that Dr. Lambert Woolley’s diagnosis was based on a mistaken reading of the laboratory report. It would appear that a person of ordinary understanding and experience can judge whether defendant acted with reasonable care when she misread the specimеn identification numbers as the test results and erroneously determined that plaintiff had an ectopic pregnancy. Yet, the court below believed that
some expert proof would be required to explain that the surgery was not medically necessary and to explain the impact of the misreading of the laboratory report in this regard. Plaintiff does not explain how she would actually present admissible evidence of malpractice or professional negligence. Nor does she explain how she would survive a motion at the end of her case in the absence of such testimony.

Finally, we emphasize the concerns expressed today in

that “the wise course of action in all malpractice cases would be for plaintiffs to provide affidavits even when they do not intend to rely on expert testimony at trial.” 168
