The two companies responsible for developing and administering the majority of teacher certification tests in the United States are Educational Testing Service (ETS) and the Evaluation Systems group of Pearson Education (formerly National Evaluation Systems, Inc.). ETS offers the Praxis tests, which are standardized across the nation ("off-the-shelf tests"), while Pearson customizes each testing program for the individual state in which it is offered. In general, it is easier to transfer certification between two states that both use the Praxis test, as the retaking of tests is usually not required in those instances. Contracts to manage state testing procedures are usually put out for bidding from different testing companies every 4–6 years.
