STARI FAQs

What is the evidence that STARI is an effective program?

STARI has been evaluated in multiple randomized controlled trials, and has earned the highest rating (ESSA Tier 1) for evidence of effectiveness. 


In one research study in Massachusetts, students who were randomly assigned to receive STARI outperformed students who received a different intervention on multiple components of literacy measured by the ReadBasix assessment (formerly the RISE). Students who received more of the curriculum (the full three units) showed more growth.



In another research study in Mississippi, students who were randomly assigned to STARI outperformed students who did not receive STARI on the state test. STARI students grew at approximately double the expected rate for middle school students. Learn more about the evidence of STARI’s effectiveness.

Decoding is a skill explicitly taught in the STARI curriculum. STARI lessons include decoding “mini-lessons”, and the texts that students read include the decoding patterns that are taught in STARI lessons. In this way, students have multiple opportunities to practice decoding, both in explicit instruction and while reading connected text. See decoding scope and sequence for more information.
