How CARS & STARS compares / aligns to other products?

No, they don’t. Not specifically, anyway, as the levelling is based on their own research and doesn't directly tie into any one system more than another.

It might help if you take a look at these documents on our website that give a brief overview of the research behind the program (and some other research done on its efficacy):

• CARS Supporting Research
• A Study for the Instructional Effectiveness of CARS & STARS
