School Reviews

What I admire most about MTS is how the school successfully balances and embraces its core traditions of fostering kindness, integrity, respect, and fairness, with its forward-thinking teaching methodologies. This philosophy distinguishes not only what MTS teaches in its forward-thinking STEM program, but what type of advanced techniques and tools it uses in its teaching, such as social-emotional learning. And through this marriage of core traditions with advanced teaching techniques, the school has fostered a respectful culture where kids become critical thinkers, explore boundaries, and take safe academic risks.
