The College Board plans an announcement Wednesday afternoon about changes to its SAT college admission test.

The SAT, last overhauled in 2005, is one of two standardized tests widely used for applications to selective colleges. The other is the ACT, which recently surpassed the SAT in the total number of student customers nationwide. But the SAT remains more widely used in the Washington region and in many states on the East and West coasts.

College Board President David Coleman, who has spoken often of his desire to improve the SAT, is expected to make the announcement in Austin. He is appearing there at an education event this week called South by Southwest Education, or SXSWedu.
