Welcome to Imagine Galileo

Imagine Galileo K-12 is a comprehensive assessment system that offers a powerful blend of convenience and flexibility. All Imagine Galileo assessments provide educators with detailed items and standard-level data to guide instruction. Imagine Galileo Benchmarks are backed by state-of-the-art Item Response Theory (IRT) to predict student state test performance with high accuracy.


Imagine Galileo is not available for students in Grade PreK. If your organization is using the Galileo ELA Benchmark as its assessment provider for Imagine Language & Literacy (IL&L), PreK-students will automatically take the IL&L Embedded Benchmark instead.
