delivered the opinion of the Court.
This appeal requires us to consider a challenge to a mandatory extended-term sentence imposed on a repeat drug offender pursu *139 ant to N.J.S.A. 2C:43-6(f). Defendant frames the issue as whether his Sixth Amendment rights were violated when the court, and not a jury, made the determination that his prior convictions supported the finding of two recidivism-based aggravating factors, which led to the court’s imposition of a sentence above the presumptive for the extended-term range. As part of our consideration of defendant’s sentencing claim, we also necessarily address the constitutionality of N.J.S.A. 2C:43-6(f).
I.
A.
On July 17, 1997, police officers from an undercover task force of the Newark Police Department arrested defendant Chris Thomas after observing him engage in two illegal drug transactions in an area known for drug trafficking. Defendant was indicted for third-degree possession of heroin, in violation of N.J.S.A. 2C:35-10(a)(1); third-degree possession of heroin with intent to distribute, in violation of N.J.S.A. 2C:35-5(b)(3); and third-degree possession of heroin with intent to distribute within 1000 feet of school property, in violation of N.J.S.A. 2C:35-7. After a five-day trial, a jury found defendant guilty of all three counts of the indictment.
The State moved for imposition of a mandatory extended term under N.J.S.A. 2C:43-6(f), which provides in relevant part:
A person convicted of manufacturing, distributing, dispensing or possessing with intent to distribute any dangerous substance ... or of distributing, dispensing or possessing with intent to distribute on or near school property or buses under section 1 of P.L.1987, c. 101 (C. 2C:35-7), who has been previously convicted of manufacturing, distributing, dispensing or possessing with intent to distribute a controlled dangerous substance or controlled substance analog, shall upon application of the prosecuting attorney be sentenced by the court to an extended term as authorized by subsection c. of N.J.S. 2C:43-7, notwithstanding that extended terms are ordinarily discretionary with the court.
At the sentencing hearing the court found, and the parties agreed, that the statutory requirements for extended-term sentencing were satisfied because defendant had seven prior convie *140 tions predominantly involving drug offenses. The court merged the counts and sentenced defendant above the statutory presumptive for the extended-term range, imposing a sentence of ten years of incarceration with a five-year period of parole-ineligibility. N.J.S.A. 2C:43-6(f), 2C:24-7(c), 2C:43-7(a)(4), 2C:44-1f(1). In determining defendant’s sentence, the court found the presence of aggravating factor three, N.J.S.A. 2C:44-1(a)(3) (“[t]he risk that the defendant will commit another offense”), and aggravating factor nine, N.J.S.A. 2C:44-1(a)(9) (“[t]he need for deterring the defendant and others from violating the law.”). The court did not find that any mitigating factors were applicable.
Defendant appealed and, in an unpublished, per curiam decision, the Appellate Division affirmed the conviction and sentence. As to the latter, the panel rejected defendant’s argument that his rights to due process and to a jury trial were violated when the sentencing court made factual findings in support of its determination to sentence defendant above the statutory presumptive sentence within the extended term range. Defendant petitioned this Court for certification, which we granted limited to the issue of defendant’s extended term sentence.
State v. Thomas,

N.J.

II.
Defendant contends that the court improperly based its findings in support of aggravating factors on facts that had not been found by the jury, thus impermissibly imposing a sentence above the maximum otherwise applicable by virtue of the jury’s verdict alone. He maintains that jury findings were necessary, even for the recidivism-based aggravating factors of three and nine,
N.J.S.A.
2C:44-1(a)(3) and (9), because the court’s findings in respect of those factors did not rest exclusively on the existence of defendant’s prior convictions.
See State v. Abdullah,
184
N.J.
497, 506 n. 2,
According to defendant the sentencing court stated that it was not relying on defendant’s prior convictions. Recognizing that his argument may be based on an over reading of a misstatement by the court or a transcription error, 1 defendant argues in the alternative that although the aggravating factors of risk of recidivism, N.J.S.A. 2C:44-1(a)(3), the extent and seriousness of a defendant’s criminal record, N.J.S.A. 2C:44-1(a)(6) (asserted by the State but not found by the court), and the need for deterrence, N.J.S.A. 2C:44-1(a)(9), are related to prior-conviction evidence, each requires findings that encompass more than the mere fact of the past conviction.
Although defendant does not advance any challenge to the mandatory extended-term statute, the State responds by first setting forth the reasons that
N.J.S.A.
2C:43-6(f) on its face should be found not to contravene any Sixth Amendment rights of a defendant. According to the State, the statute is not vulnerable under

We begin our analysis of Sixth Amendment case law with a matter that originated in this State. In
Apprendi v. New Jersey,
530
U.S.
466, 468-69, 120
S.Ct.
2348, 2351, 147
L.Ed.2d
435, 442 (2000), the United States Supreme Court considered a Sixth Amendment challenge to New Jersey’s “hate crime” statute that had permitted imposition of a sentence beyond the statutory maximum if the court found, by a preponderance of the evidence, that the defendant had acted “with a purpose to intimidate an individual or group of individuals because of race, color, gender, handicap, religion, sexual orientation, or ethnicity.”
N.J.S.A.
2C:44-3(e) (repealed 2001). In a five to four decision, the Supreme Court declared that statute to be violative of a defendant’s Fourteenth Amendment due process rights and the notice and jury trial guarantees of the Sixth Amendment, holding that
“[o]ther than the fact of a prior conviction,
any fact that increases the penalty for a crime beyond the prescribed statutory maximum must be submitted to a jury, and proved beyond a reasonable doubt.”

The majority opinion in
Apprendi, supra,
authored by Justice Stevens, and joined by Justices Scalia, Souter, Thomas, and Ginsburg, described
Almendarez-Torres
as “representing] at best an exceptional departure from the historic practice” of requiring that sentence-enhancing factors be included in the indictment, submitted to the jury, and proved beyond a reasonable doubt. 530

*144 Nonetheless, Apprendi authorized an exception permitting courts to use prior convictions in sentence-enhancement determinations and, twice since, the Court restated its holding in Apprendi with the prior-conviction-exception language intact. See Blakely v. Washington, 542 U.S. 296, 813, 124 S.Ct. 2531, 2543, 159 L.Ed.2d 403, 420 (2004) (holding that Washington statute, which contained a provision allowing for sentence enhancement if defendant acted with “deliberate cruelty,” constituted offense element that required jury finding); United States v. Booker, 543 U.S. 220, 226-27, 125 S.Ct. 738, 746, 160 L.Ed.2d 621, 639 (2005) (holding that “the Sixth Amendment as construed in Blakely ” applied to courts’ implementation of federal sentencing guidelines). Blakely, supra, held that a defendant’s Sixth Amendment rights are violated whenever the sentence that is imposed exceeds the maximum sentence authorized by virtue of the jury verdict or the defendant’s admissions at a plea hearing, unless the sentence enhancement is either the result of the fact of a prior criminal conviction or the defendant had consented to judicial fact-finding for sentencing purposes. 542 U.S. at 301, 303, 124 S.Ct. at 2536, 2537, 159 L.Ed.2d at 412, 413; see also Booker, supra, 543 U.S. at 243-44, 125 S.Ct. at 755-56, 160 L.Ed.2d at 650 (applying Blakely with prior-conviction exception intact).
On the heels of
Blakely
and
Booker,
however, a majority of the Court reignited debate about the viability of
Almendarez-Torres
in
Shepard v. United States,
544
U.S.
13, 125
S.Ct.
1254, 161
L.Ed.2d
205 (2005). The question in
Shepard, supra,
was whether a sentencing court, acting pursuant to the Armed Career Criminal Act (ACCA), 18
U.S.C.A.
§ 924(e) (2000 & Supp. II 2002), could examine police reports or complaints when determining whether a prior guilty plea to burglary constitutes a conviction of a “violent felony.” 544
U.S.
at 15, 125
S.Ct.
at 1257, 161
L.Ed.2d
at 211. The ACCA mandates a fifteen-year minimum sentence for any person who has committed a specified federal firearms violation so long as that person has three prior convictions for “violent felonies.”
Ibid.
The ACCA includes “burglary” in its definition of a “violent felony.” 18
U.S.C.A.
§ 924(e) (2000 & Supp. II 2002).
*145
Previously the Court had held that the ACCA’s use of the term “burglary” includes only “generic burglary,” which requires that three elements be present: “[i] unlawful or unprivileged entry into, or remaining in, [ii] a building or structure, [iii] with intent to commit a crime.”
Taylor v. United States,

Similarly, in
Shepard, supra,
authored by Justice Souter, and joined in full by Justices Stevens, Sealia, and Ginsberg, a plurality “limit[ed] the scope of judicial factfinding on the disputed generic character of a prior plea, just as
Taylor
constrained judicial findings about the generic implication of a jury’s verdict.” 544

Justice Thomas joined in the Court’s holding, but declined to join the part of the opinion that he deemed inconsistent with his belief that to allow a court to determine any sentence enhancing factor, including recidivism, would cause “constitutional error.”

In the wake of
Blakely,
the use of presumptive sentencing in this State was challenged and eliminated in
State v. Natale,
184
N.J.
458,
Natale
considered whether
Blakely’s
holding, that “a sentence based on judicial factfinding that exceeds the maximum sentence authorized by either a jury verdict or a defendant’s admissions at a plea hearing runs afoul of the Sixth Amendment right to trial by jury,” was applicable to our system of presumptive sentencing.

The companion case of
State v. Abdullah,
184
N.J.
497, 499,
In a footnote that has taken on enhanced significance in this appeal, we added that “we might have come to a different result” had the sentencing court “specifically found that aggravating factors (3), (6), and (9) related to the defendant’s prior convictions as the basis for increasing defendant’s [burglary] sentence.”
Id.
at 506 n. 2,
[aggravating factors (3), (6), and (9), arguably, are inextricably linked to the recidivism exception. In a discretionary sentencing system in which the court decides the weight to give to a prior criminal conviction and how high on the scale to increase the sentence, the court naturally would consider the risk a defendant will re-offend and the need to deter. We do not know what value a court can give to a criminal conviction in our system without considering those factors.
*149 [Ibid.]
Our decision in Abdullah did not resolve whether a court’s finding of any of the so-called “recidivism” aggravating factors of (3), (6), and (9) could be regarded as based exclusively on the “fact” of a prior conviction, or whether a finding of any of those factors necessarily encompassed additional fact-finding made impermissible under Blakely and Apprendi. Rather, we anticipated, without deciding, the issue raised in the present appeal: whether a sentencing court’s finding of factors (3) (risk of repeat offense, N.J.S.A. 2C:44-1(a)(3)), and (9) (need for deterrence, N.J.S.A. 2C:44-1(a)(9)) fit within Blakely’s prior-conviction exception.
The State, and the Attorney General as amicus, urge this Court to conclude that it is permissible for a sentencing court to find those aggravating factors as derivative of finding the fact of the prior conviction. The defendant contends that a finding of factors (3), (6), and (9), though related to prior-conviction evidence, requires findings in addition to the fact that defendant has been convicted of a crime and, therefore, a jury must find those factors before they can be used to sentence a defendant above the presumptive for the range. We therefore consider two issues in respect of defendant’s sentencing in light of the present status of Blakely’s prior-conviction exception: use of defendant’s prior convictions to trigger sentencing under N.J.S.A. 2C:43-6(f), and use of his prior convictions when finding that aggravating factors (3) and (9) support imposition of a sentence above the presumptive applicable to the enhanced-sentence range.
TV.
A.
N.J.S.A.
2C:43-6(f) requires a sentencing court to impose an enhanced-range sentence when the prosecutor applies for such relief. The language of 2C:43-6(f) clearly indicates that the Legislature meant enhancement to be mandatory: a person
“shall
upon application of the prosecuting attorney
be sentenced by the
*150
court to an extended term.” See generally
Norman J. Singer, 1A
Sutherland Statutes and Statutory Construction
§ 25:4 (6th ed.2000)(noting that “[w]hether a statute should be given mandatory ... effect is ... a question of statutory construction to which all of the rules and principles of construction are applicable ... [; however,] [u]nless the context otherwise indicates a use of the word ‘shall’ (except in future tense) indicates a mandatory intent.”);
see also Harvey v. Bd. of Chosen Freeholders,
30
N.J.
381, 391,
That some question the viability of
Almendarez-Torres
does not provide a principled basis for invalidating
N.J.S.A.
2C:43-6(f). The Supreme Court has held that a court, as opposed to a jury, may make the discrete finding of the existence of a prior conviction when enhancing a defendant’s sentence without violating a defendant’s Sixth Amendment rights,
Almendarez-Torres, supra,
523
U.S.
at 226-27, 118
S.Ct.
at 1222,
In sum, the State began its argument by asserting that the statute is constitutionally sound. We agree. N.J.S.A. 2C:43-6(f) *152 operates as a sentence enhancer on the basis of a judicial fact-finding that is authorized under Apprendi and Blakely, to wit, the finding of prior convictions. Accordingly, we hold that no Sixth Amendment violation resulted from the sentencing court’s finding of the fact of defendant’s prior convictions, which required imposition of a mandatory enhanced sentence under N.J.S.A. 2C:43-6(f). We turn, therefore, to defendant’s sentencing within the enhanced-term range.
B.
Natale, supra,
held that its principles would be given “pipeline retroactivity” effect. 184
N.J.
at 494,
Our
Natale
remedy was constructed on the premise that we would no longer require sentencing courts to commence their exercise of sentencing discretion from the starting point of a presumptive sentence.
Id.
at 487,
That said, we do not base our holding on that consideration alone. As noted, the Natale remedy for the New Jersey Code of *153 Criminal Justice, post-Blakely, did not Mnge on discrete determinations of whether a particular sentencing factor must be decided by a jury, or may be decided by a sentencing court. We see no reason now to risk constitutional error by straining to interpret which past sentencing decisions utilizing factors (3) and (9) fit within our best prediction of how far we may stretch the presently allowed prior-conviction exception. Rather, it is more prudent, constitutionally, to construe narrowly the “facts” that Blakely’s prior-conviction exception permits a sentencing court to consider. Therefore, we hold that that judicial fact-finding must be limited to the finding of the existence of the prior conviction. For defendants sentenced prior to Natale, we have no confidence that any who were sentenced above the presumptive sentence on the basis of aggravating factors (3), or (6), or (9) were sentenced exclusively on the mere judicial fact-finding of the existence of a prior conviction.
Indeed, implicit in a sentencing court’s assessment of the defendant’s risk of recidivism (factor (3)), the seriousness and extent of a defendant’s prior criminal record (factor (6)), and the need to deter defendant and others (factor (9)) is a qualitative assessment that we want and expect the court to make. A court’s findings assessing the seriousness of a criminal record, the predictive assessment of chances of recidivism, and the need to deter the defendant and others from criminal activity, do all relate to recidivism, but also involve determinations that go beyond the simple finding of a criminal history and include an evaluation and judgment about the individual in light of his or her history.
See, e.g., State v. Dunbar,
108
N.J.
80, 96-97,
In conclusion, we hold that a remand for defendant’s re-sentencing is required. In accordance with
Natale, supra,
the court should re-determine defendant’s sentence within the extended-term range based on aggravating and mitigating factors found to be present. 185

The judgment of the Appellate Division in respect of defendant’s sentence is reversed and this matter is remanded for resentencing.

Notes
Defendant is referring to the court’s statement recorded and transcribed as follows: "As to the motion for extended term, I’m not counting the defendant’s prior criminal record because I’m taking that into consideration in granting the motion for an extended term.” In context, it appears that the court simply was indicating that it would not be impermissibly counting defendant’s criminal history twice.
