Overview

An ISIP™ assessment will be given automatically each month. For example, if a student logs in on Sept. 1st an ISIP assessment will be given, but if the student doesn't log in until Sept. 15th an ISIP assessment will still be given because it is the first time the student has logged in for the month. This will result in 8-12 automatic assessments per year, depending on the length of each district's school year. Additional On Demand assessments can be given at any time during the school year.

Computerized Adaptive Testing (CAT)

ISIP Math utilizes computerized adaptive testing that accurately reflects the mathematical ability level of each student and measures growth over time.

Adaptive assessments use interactive content to measure a student's overall mathematical ability. Test questions range from easy to hard in several math skill areas for pre-K through 8th grade students. To identify the student's overall mathematical ability, the difficulty of the test questions presented changes with every response. If a student answers questions correctly, ISIP Math presents more challenging questions until the student shows mastery or responds with an incorrect answer. When a student answers a question incorrectly, ISIP Math will present less difficult questions until the student begins answering correctly again. The ability score shows how a student is doing compared to their previous performance and to other students at the same grade level.

National Norms for ISIP Math

National norms for ISIP Math are currently provided for students in grades pre-K through 8th. These norms enable teachers, parents, and students to know how their students' scores compare with a nationally representative sample of children in their particular grade. The norming samples were obtained as part of Istation's ongoing research in assessing mathematics ability.

Ability Index

ISIP Math uses a measurement scale that aligns student performance levels with test question difficulties. The scale used is divided into equal parts. These parts are called ability indices. All test questions are placed on the ability index scale according to their difficulty. Each increasing ability index is assigned a numeric value that indicates a higher level of difficulty. As a student takes an ISIP Math assessment, he or she is presented with test questions of varying ability indices or levels of difficulty. Once ISIP Math determines the difficulty level at which the student is able to perform, the test ends and the student is assigned an overall mathematical ability index.
