You might point out to the school that ALEKS is also set up to use with the RTI process (remediation/special ed), and if the school gets a school-wide license, it might really simplify things for teachers who need to provide additional support for kids who are behind the curve as well as providing a simple means for meeting the needs of students who are ahead.
The program pre-tests, post-tests, and provides basic explanations, freeing the teacher from "grunt work" tasks like grading papers, keeping separate records of differentiated assignments, creating worksheets, and acting as a "talking textbook" - things that aren't necessarily the best use of valuable teacher time.
If you want this resource for your kids, sell it to the school in terms of what it will do for the school and the teachers as well as for your children.
