The Educators Behind ETT

Every ETT question and course is built and reviewed by educators from leading universities. More than 40 ETT specialists develop our SAT®, ACT®, and AP® materials, bringing deep subject expertise and years of test-prep experience to everything students practice with.

Credentials That Stand Behind Every Question

Our content is developed by a team of more than 40 ETT specialists, and every one of them holds a degree from an accredited university — not a single undergraduate among them. They join the team through a rigorous interview process and bring deep subject-matter expertise to the material students practice with.

Our educators have graduated from institutions including:

  • Harvard, Yale, Princeton, Stanford, and Columbia
  • University of Pennsylvania, Cornell, Brown, Dartmouth, and the University of Chicago
  • Johns Hopkins, Duke, Carnegie Mellon, UC Berkeley, and UCLA
  • University of Michigan, USC, NYU, Amherst, Rice, Georgia Tech, and more

Expertise Across Every Subject We Cover

The team spans the full range of tested material, so each question is designed by someone who specializes in that area:

  • Math & Quantitative: mathematics, applied mathematics, statistics, and engineering specialists
  • Reading & Writing: English, history, philosophy, and humanities scholars
  • Sciences: biology, chemistry, physics, and computer science experts for AP coursework

How Our Content Is Built and Reviewed

Our specialists study official released exams to understand the format, difficulty, and reasoning each section tests. They design questions to match those standards, and every item is cross-reviewed by the team before it reaches students. Our Digital SAT® material is updated monthly to reflect the latest test trends, so what you practice always mirrors the current exam.

The result is practice that feels like the real thing — built by people who know exactly what the real thing looks like.
