1 Validity Evidence for the Orleans-Hanna Algebra Prognosis Test Jack B. Monpas-Huber, Ph.D. Director of Assessment & Student Information

2 How well does Orleans-Hanna predict success in Compression or Algebra? Fall 2010 1st Trimester 7th Grade Math Course Grades by Orleans-Hanna Score Was good to allow students with a range of O-H scores to enter Compression to test its validity predicting performance in the class Most of the As in Compression scored at least 35, but B students represent a broad range of O-H scores Thus students with scores lower than 35 could still succeed in Compression Initial “cut score” for recommended placement in Compression was 35

3 How well does Orleans-Hanna predict success in Compression or Algebra? Fall 2010 1st Trimester 7th Grade Math Course Grades by Orleans-Hanna Score Most of the students getting As in Compression scored at least 35 on the O-H Boxplots are designed to show range and variation but in this case useful for seeing that generally higher O-H scores associated with generally higher Compression grades

4 How well does Orleans-Hanna predict success in Compression or Algebra? Fall 2010 1st Trimester 7th Grade Math Course Grades by Orleans-Hanna Score At Einstein, students with a wide range of OH scores still received As and Bs in Compression Initial “cut score” for recommended placement in Compression was 35

5 How well does easyCBM predict success in Compression or Algebra? Fall 2010 1st Trimester 7th Grade Math Course Grades by Winter easyCBM Score

6 How well do easyCBM and Orleans-Hanna predict success in Compression?
