Research Behind Reflex

Reflex produces real results.

Reflex uses research-proven methods and innovative technology to provide the most effective math fact fluency solution available. Across multiple grade levels, standardized tests, and assessments—students who use Reflex score higher and grow faster than their peers. Studies show statistically significant, positive results for Reflex users and meet ESSA’s Moderate Evidence requirements. Independent, third-party review for two studies is also available at The National Center for Intensive Intervention (NCII).

What People Say About Reflex

At the beginning of the year one of my second graders was solving six addition problems in two minutes. That student is now solving 30 addition problems in two minutes. He is also able to solve 30 subtraction problems in two minutes. His fluency started to shoot up after starting Reflex.

Awesome, awesome, awesome! Reflex is by far the best program out there. All but one of my students scored within the targeted norm range on our district calculations assessment. This was an increase from 50% on the fall assessment.

Dear Awesome People of Reflex: I just wanted to say thank you for all the math stuff you did for my class. My favorite game is: all of the games. Thanks again for making me stronger and how much fun you made me have.

Every day is a success story with Reflex! The kids LOVE it and ask if they can play every day. Even my kids who are at 100% fluency still want to play and see how high they can get their scores.

Fluency has always been a struggle because the foundation wasn’t there when learning other content such as subtraction with regrouping. Since Reflex, my students’ fluency is so strong that they are excelling in all areas of math! I am so proud and happy to have found Reflex!
