OPINION OF THE COURT
Alphonse Howard (“Howard”) appeals the District Court’s determination that he was a career offender under U.S.S.G. § 4B1.1. He argues that the District Court erred in relying on uncertified documents in determining that his two previous drug convictions were felonies. We conclude that the District Court was correct in referring to uncertified documents to establish prior convictions for sentencing purposes. Accordingly, the District Court’s judgment will be affirmed.
I.
On March 15, 2006, law enforcement officials executed a search warrant on 5511 Haverford Avenue in Philadelphia, Pennsylvania. This residence, which was located within 1,000 feet of a school, was used by Howard to grow marijuana. Howard ■was arrested and subsequently pleaded guilty to: (1) manufacturing, and possession with intent to distribute, a mixture and substance containing a detectable amount of marijuana, in violation of 21 U.S.C. §§ 841(a)(1) and (b)(1)(D); and (2) manufacturing, and possession with intent to distribute, a mixture and substance containing a detectable amount of marijuana within 1,000 feet of a school, in violation of 21 U.S.C. § 860(a).
On September 8, 2008, at Howard’s sentencing hearing, he objected to the conclusion of the Pre-Sentence Report that he was a career offender. He also argued that the government had impermissibly introduced uncertified documents as proof of prior drug convictions. These prior convictions, if established as felonies, would classify Howard as a career offender under U.S.S.G. § 4B1.1 and would enhance his offense level from 13 to 32.
Howard had previously been convicted on two separate occasions in Philadelphia County for possession with intent to distribute a controlled substance. He was sentenced to nine months’ probation for his March 7, 2000 conviction and one year of probation for his September 22, 2000 conviction. At the sentencing hearing in this case, the government offered certified copies of these convictions to establish that Howard was a career offender for sentencing purposes. The certified copy of the September 22, 2000 conviction, however, did not indicate whether Howard had pleaded guilty to a misdemeanor for possession of a controlled substance or a felo *271 ny for conspiracy involving a controlled substance. The government subsequently conceded that the certified copy of conviction was ambiguous as to the exact offense to which Howard pleaded guilty, but argued that the Municipal Court of Philadelphia County Criminal Docket (“M.C. Docket”) relating to Howard’s September 22, 2000 case reflected that he had pleaded guilty to a felony. The M.C. Docket was not a certified document. The District Court granted the government’s request to continue the sentencing hearing in order for the government to determine whether the transcripts from the September 22, 2000 guilty plea were available.
On December 3, 2008, the District Court re-convened the sentencing hearing. The government stated that the transcripts from the September 22, 2000 guilty plea were unavailable. Notwithstanding that unavailability, the District Court relied on the incomplete certified record of conviction and the uncertified M.C. Docket entries to conclude that Howard’s September 22, 2000 guilty plea had indeed been for a felony, and thus that the career offender enhancement under U.S.S.G. § 4B1.1 was appropriate. Howard was then sentenced to a prison term of 148 months. This timely appeal followed.
II.
The District Court had jurisdiction over this criminal matter pursuant to 18 U.S.C. § 3231. This Court has jurisdiction pursuant to 28 U.S.C. § 1291 and 18 U.S.C. § 3742. The question of what documents a district court may rely on to determine the nature of a prior conviction and the scope of a district court’s authority to make factual findings are questions of law,
Shepard v. United States,
III.
Howard argues that the evidence presented by the government at sentencing was insufficient to establish that he was a career offender within the meaning of U.S.S.G. § 4B1.1. 1 Howard does not deny that he has two previous drug convictions. Instead he challenges the evidence the District Court relied on in making the determination that his September 22, 2000 conviction was a felony. Specifically, he argues that the Court improperly relied on the incomplete certified conviction and the uncertified M.C. Docket in determinating his career offender status. Howard argues on appeal that a court must rely only on certified documents as evidence of prior convictions. We disagree.
The Federal Rules of Evidence do not apply in sentencing proceedings. Fed.R.Evid. 1101(d)(3). Instead, evidence presented at sentencing must have a “ ‘sufficient indicia of reliability to support its probable accuracy.’ ”
United States v. Miele,
In
Watkins,
the defendant argued “for a
per se
rule that certified copies of the judgments of conviction are required in every case before a sentencing court may determine that the defendant’s prior convictions are for ‘violent felonies’ ” under the Armed Career Criminal Act (“ACCA”).
Id.
We specifically declined to adopt an “inflexible”
per se
rule.
Id.
Instead, we held that the district court did not err in relying on a presentence report to “ascertain with certainty the statutes of conviction .... ”
Id. See also United States v. Chavaria-Angel,
The Eleventh Circuit was faced with a similar question in
United States v. Acosta,
In satisfying its evidentiary burden to prove career offender status, the government may rely on certified copies of convictions. However, a court may also confirm a defendant’s previous convictions by relying on the terms of the plea agreement, the charging document, the transcript of colloquy between judge and defendant, or other comparable judicial records of sufficient reliability.
See Shepard v. United States,
In determining that Howard’s September 22, 2000 conviction was a felony, the District Court in this case relied on an incomplete certified conviction record and M.C. Docket entries, both of which are
*273
“records of the convicting court.”

Shepard,
These docket entries are the type of judicial records that are permissible for sentencing courts to use to establish past convictions for sentencing purposes. The fact that the certified conviction was incomplete and ambiguous as to the level of Howard’s offense did not prohibit the District Court from looking to other reliable judicial records to establish the type of crime for which he was convicted. 3
IV.
For the foregoing reasons, we will affirm the District Court’s judgment.
Notes
. U.S.S.G. § 4B1.1 provides that a defendant is a career offender for sentencing purposes if
(1) the defendant was at least eighteen years old at the time the defendant committed the instant offense of conviction; (2) the instant offense of conviction is a felony that is either a crime of violence or a controlled substance offense; and (3) the defendant has at least two prior felony convictions of either a crime of violence or a controlled substance offense.
. The M.C. Docket entry provided the District Court with evidence of the specific statute under which Howard was charged.
. We do note, however, that the government's ability to rely on various documents from the judicial record to establish past criminal convictions does not lighten its burden of proving the prior conviction by a preponderance of the evidence.
