Growth Models

The importance of growth models is to determine the student's yearly achievement by providing an accountability system. The interest of growth models lies in those students who display a mastery of grade-level and are above proficiency based on previous scores. The old scores are what is used to create predicted scores for a given year. The growth models were initially reauthorized in 1965 by the Elementary and Secondary Education Act and again in 2001, as a byproduct of No Child Left Behind Act of 2001 (Ryser, & Rambo-Hernandez, 2014).
