Major Findings:

  • CORE-Plus students performed significantly less well on math placement test and ACT-M than did traditional students
  • Change in performance was observed immediately after switch
  • Score trends throughout CORE-Plus years actually decreased slightly – Inconsistent with a teacher learning-curve hypothesis
  • CORE-AP students fared much better, but not as well as the traditional – AP students – Both sample sizes were low
