2004

Dr. Sabatini began working on RISE at ETS in collaboration with the SERP Institute

School districts in Massachusetts noticed that many of their middle school students were arriving in 6th grade with weak reading skills, but the schools were not equipped to identify students’ exact reading skills weaknesses—or what to do about them.

2007

One of the first large scale administrations in a large Massachusetts school district

This allowed RISE to be field tested for the first time with students in entire middle schools.

2010

$115M Department of Education IES Reading for Understanding (RfU) Initiative

This funding allowed for the expansion of the assessment to include more grade levels including elementary school starting from Grade 3 to high school.

2012

Field testing expansion with administrations at a large school district in Maryland

The tests allowed ETS and the SERP Institute to refine RISE based on user feedback and analysis of the data.

2016

National norming study in grades 3-12

After that the RISE (Reading Inventory and Scholastic Evaluation) evolved into its current form under the name ReadBasix.
