Juniors in Michigan’s public high schools will be able to take the SAT college admission test for free starting in 2016, ending the dominance there of a rival test, the state announced Wednesday.

Michigan chose the SAT over the rival ACT after a competitive bidding process. The College Board, a nonprofit organization based in New York, which oversees the SAT, won a three-year contract worth about $17.1 million. It was a significant victory for the College Board as it prepares to roll out an updated version of the SAT.

Currently, the ACT dominates the Michigan testing market. A Washington Post analysis in March found that about 120,000 Michigan students in the Class of 2013 took the ACT, compared with 4,300 who took the SAT.

Testing contracts with numerous states, including Michigan, have helped the ACT become the most widely used admission test in recent years. But the College Board is seeking to grow the SAT’s market share.

The SAT is offered for free to students in D.C. public schools.
