About Us

Thousands of test-takers sit for the TOEFL® or Duolingo English Test (DET) every year, and not all of them get their score. We wanted to change that; which is why our small team of motivated educators launched TST Prep in January 2019. TST Prep is an online-based language test solution platform designed to provide an interactive learning experience for students who need to prepare for the TOEFL or DET and improve their English fluency. Our student-centered approach not only provides test strategies and score-building practice activities but is also powered by a community-driven learning environment where teachers are accessible and fellow test-takers support you every step of the way to your dream score.

Our Principles

It is our responsibility to provide all of the necessary practice, feedback, and support each test-taker requires to achieve their goal.

Our team of professional teachers for the TOEFL and Duolingo English Test work alongside our community of passionate test-takers to deliver high-quality test practice and courses to ensure that you get your score as quickly and as easily as possible.

We believe in our mission, and to achieve our goals, our staff and our students must abide by the following principles:

Each student is an individual

Students, teachers, and staff must be treated with the personalized attention he or she needs to reach their potential.

Growth requires active thought and consistent practice

There are no shortcuts to success. Strategies are helpful, but consistent and thoughtful work is the key to achievement.

Personalized feedback is essential

The more feedback we receive on our work from a trained professional or AI system, the better we will perform.

Practicing without a plan leads to failure

Plans often fall apart in the process, but the structure they provide will help us know where to go and the best route forward.

We are all accountable

Teachers, staff, and students alike must take responsibility for our actions if we are to learn and grow from our mistakes.

We promote authentic communication and empathy

We care about each other and we like to communicate with calmness, with empathy, and with authenticity.

Our Mission

To provide daily practice, consistent feedback, and reliable support so students can stop wasting time, get their TOEFL or DET test score as quickly and as easily as possible, and improve their lives.
