The questions on your mind.

When did Open Door start?
down blue arrow

Open Door started in 2013. Today, Open Door offers two programs - Mastery Assessments and Thinking Classroom - to schools. Open Door is about to launch two new products - Unbox and Thinksheets - for individual parents soon.

What is the difference between Mastery Assessments and Thinking Classroom program?
down blue arrow

Both the programs have beautiful questions at their core. While Mastery Assessments help schools ensure strong conceptual understanding after a topic is taught, Thinking Classroom is a set of workbooks that transform a classroom with a lot of monolog into a lot of self-thinking.

Who are we?

Open Door's programs are designed a team of young graduates from some of the finest universities - such as the IITs and NITs - in India. This team consists of a group of thinkers who live and breathe science and math. When they look around themselves, they do not see a table, a wall or a book. They see opportunities to design beautiful science and math questions.

Each of Open Door's departments is like an instrument, which when plays together to produce a wonderful symphony.

Over the last 7 years, Open Door team has been working to increase the thinking in many classrooms. Open Door's programs are currently making 150000+ students think more than before.
