No. 04-40778.

Summary Calendar.

United States Court of Appeals, Fifth Circuit.

Decided Sept. 30, 2005.

*298Tracey M. Batson, Assistant U.S. Attorney, U.S. Attorney’s Office, Eastern District of Texas, Plano, TX, for Plaintiff-Appellee.

John Thomas Haughton, Law Office of John T. Haughton, Denton, TX, for Defendant-Appellant.

Before REAVLEY, DAVIS and PRADO, Circuit Judges.

PER CURIAM: *

Rolando Hernandez appeals from his conviction by guilty plea of conspiracy to manufacture, distribute, or possess with intent to manufacture or distribute methamphetamine. Hernandez contends that the district court violated the Sixth Amendment by basing his sentence on findings beyond those he admitted when he pleaded guilty, pursuant to *Blakely v. Washington,*542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004), and *United States v. Booker,*543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). Hernandez contends that he received ineffective assistance of counsel in conjunction with his guilty plea because counsel erroneously advised him that his criminal history would not be used against him at sentencing. He alleges that he advised his second attorney about his misunderstanding with original trial counsel regarding the Sentencing Guidelines, and he argues that his second attorney should have filed a motion to withdraw his plea. Finally, Hernandez argues that his second attorney was ineffective for failing to present a *Booker*argument at sentencing.

Regarding *Blakely*and *Booker,*Hernandez specifically challenges the district court’s findings that his prior sentences were unrelated for the purpose of finding him a career offender, that he was a career offender, and that he possessed a firearm. Hernandez, however, does not argue any facts to suggest that his prior *299sentences were related for guideline sentencing purposes.

“There is no Sixth Amendment violation with respect to post-trial consideration of career offender status.” *United States v. Guevara,*408 F.3d 252, 261 (5th Cir.2005). Other than a defendant’s age, “the determinations made in the course of a career offender classification are all questions of law,” *id.,*and thus are not subject to the requirements of *Booker. Id.*Hernandez can demonstrate no error, plain or otherwise, regarding whether his sentencing as a career offender violated *Blakely*and *Booker.*Because Hernandez has not shown reversible error regarding his sentencing as a career offender, his remaining sentencing contentions need not be addressed.

Hernandez’s argument regarding counsel’s allegedly flawed advice about the sentencing guidelines implicates Hernandez’s understanding of the consequences of his plea, which implicates the voluntariness of the plea. *See Boykin v. Alabama,*395 U.S. 238, 243-44, 89 S.Ct. 1709, 23 L.Ed.2d 274 (1969). The record is not sufficiently developed for us to address the merits of that ineffective counsel claim on direct appeal, so we do not consider it. *See United States v. Fry,*51 F.3d 543, 545 (5th Cir. 1995). Because Hernandez’s *Blakely/Booker*argument is unavailing, counsel was not ineffective for failing to raise it. *See Koch v. Puckett,*907 F.2d 524, 527 (5th Cir.1990)

AFFIRMED.
