20-25 minutes, tops for the levels up to 6th grade. Can't imagine that 7th/Pre-Algebra would be much longer.

You pick the grade level that makes most sense & ALEKS will require an assessment on first use by your child. If your child scores sufficiently high enough to warrant using the next level, you can easily move him up. ALEKS recommends that if your child initially hits 90% on the assessment to move to the next level.
