In 1982, teachers Sam and Lori Mammen started ECS Learning Systems at their living room coffee table in Bulverde, Texas. From the beginning, our company mission has been to create quality, innovative K-12 resources that make teaching easier.


As a leading publisher of state-specific test-prep materials, ECS is pioneering the concept of Integrated Test Prep. This approach encompasses six essential stages of test preparation: diagnose, teach, practice, evaluate, remediate, and reinforce. Traditional test-prep programs focus solely on targeted test practice, creating an imbalance that compromises sound teaching practices. With the TestSMART® and STAAR MASTER® series, teachers can embark on a path to Integrated Test Prep. This balanced approach supports a strong curriculum, varied instructional methods, and targeted test practice.

We have also compiled the best resources available for Spanish/English and Special Education teachers and students. Our comprehensive product catalog includes thousands of activity books, workbooks, test-preparation materials, and other resources for reading, writing, and thinking skills.


We treat our coworkers like family and our customers like good neighbors. We use our company resources wisely, so we can focus on creating quality products that we would want teachers to use with our own children. We love teachers, so we strive to make materials that make teaching easier. And, we always have time to lend a hand in our community.


Our enduring commitment is to provide teachers research-based educational content that makes teaching effective and easy. We uphold the highest integrity standards in the development of our products.
