An independent research organization, Human Resources Research Organization (HumRRO), established these tables with a linking study, which is a psychometric method to predict scores on one test (e.g., ILEARN) from scores on another test (e.g., the Exact Path diagnostic).

When educators ask, “Based on a student’s Exact Path diagnostic score, how is the student likely to perform on ILEARN?” this research study answers that question through a psychometric method known as linking. The provided tables can be used to predict student performance on ILEARN based on students’ Exact Path diagnostic scores.
