What is the appropriate or normal or common or ideal percentage that you would want a student to score on a unit pretest for math in general and algebra in particular?
According to the Diagnostic Testing / Prescriptive Instruction model (DT-PI) discussed in the book "Developing Math Talent" and summarized at http://www.win.tue.nl/~wstomv/quotes/developing-math-talent.html , a student should take tests at progessively more difficult levels until he or she scores below the 85th percentile.
