Overview

An ISIP™ assessment is given automatically each month. For example, if a student logs in on September 1st an ISIP assessment will be given, but if the student doesn't log in until September 15th an ISIP assessment will still be given because it is the first time the student has logged in for the month.

This automatic administration results in 8 to 12 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 integrates computerized adaptive testing that accurately reflects the reading ability level of each student and measures growth over time.

Adaptive assessments use interactive content to measure a student's reading ability and skill development. Test questions range from easy to hard for each reading domain based on pre-K through grade 3 Spanish reading language arts standards To identify the student's overall reading ability and individual skill ability, the difficulty of the test questions presented changes with every response. If a student answers questions correctly, ISIP presents more challenging questions until the student shows mastery or responds with an incorrect answer. When a student answers a question incorrectly, ISIP 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 Lectura Temprana

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 are obtained as part of Istation's ongoing research in assessing reading ability.

Ability Index

ISIP assessments use a measurement scale that aligns student performance levels with test question difficulties on the same scale. 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 assessment, he or she is presented with test questions of varying ability indices or levels of difficulty. Once ISIP determines the difficulty level at which the student is able to perform, the test ends and the student is assigned an overall reading ability index, as well as ability indices for individual subtests.

Since ISIP is adaptive and the test questions are displayed based on student performance, not age or grade, identical ability indices across grades mean the same thing. For example, when a first grader receives the same ability score as a third grader, these results indicate that the students are performing at the same level.

This ability index can be used by teachers to inform instruction around their students' strengths and weaknesses. Targeted instruction leads to better performance and maximum growth.

ISIP Subtests

Each student will begin the school year by taking an assigned set of ISIP subtests based on her/his grade level. More advanced or more basic subtests will be added based on the student's overall reading ability index.
