Norm-Referenced Assessments

These assessments compare a student’s score with a similar group of students who have taken a comparable assessment.

ERB: Comprehensive Testing Program, 4th Edition (CTP 4) is a rigorously designed series of assessments in reading, writing, and mathematics developed to help educators collect critical educational data that answers the questions of administrators, teachers, and parents about achievement. CTP 4 is not one test, but a set consisting of a series of multiple-choice and open-ended question tests administered to groups of students over the course of several days, either in the spring or the fall. CTP 4 has 10 levels; a different level is used with each grade from 1 through 11.
