In my last post, I made this argument:

if we want to accurately assess student growth and achievement, we must use a criterion-referenced and valid instrument, administered to all students in Pennsylvania, under controlled conditions.  And the assessment must be linked to what we’re teaching … the PA standards.  

Only the PSSA hits all of these criteria.  In the attached chart, I show how I arrived at that conclusion.  How do the tests that are widely used in our classrooms stack up?    For those who like charts … enjoy!  (Corrections welcome — leave a comment)
