The Educational Research Institute of America says:
Students using STARS instruction showed significant improvement on foundational reading skills. The CARS & STARS treatment group for year 3 scored 40% higher on the post-test than did the control group. Struggling learners showed especially strong growth with scores that jumped 40-79% in just 18 weeks.
