Performance Series Internet-delivered assessment is a Standards-based Adaptive Measurement – a computer adaptive assessment modified to measure the different academic objectives of individual state standards. Its goal is to give immediate diagnostic information to each teacher, including learning objectives a student has not completed,
and the academic gains made by individual and groups of students. Additionally, the administration can access scores for the entire district as well as each school, with full desegregation abilities.         

Since assessment plays an important role in driving instruction, it is important that the assessment actually measure a student’s knowledge each year. The average classroom has a seven-grade breadth of knowledge, but historically assessments have only measured knowledge within one grade. Only the students operating at grade level were actually measured by previous assessments. Additionally, there was no way for teachers or tutors to ascertain the true level of knowledge for students performing outside a given grade level; students could be anywhere between half a grade to seven grades behind or ahead of their peers. Teachers/tutors were unable to properly remediate or challenge students, as they had no way to determine the true level of their academic competence.
