Maryland Lt. Gov. Anthony G. Brown (D) on Wednesday promised that he would cap annual tuition increases at public universities at 3 percent throughout his four-year term if elected governor.

Brown’s pledge would maintain the same policy goal of his boss, outgoing Gov. Martin O’Malley (D), who has made college affordability a priority since taking office in 2007.

After several years of sizable increases, tuition at Maryland universities was frozen for four years under O’Malley and has grown modestly in the latter part of his tenure. O’Malley has proposed allowing a 3 percent increase in the coming academic year.

Since 2008, Maryland has experienced the second smallest growth in the tuition and fees in the nation, adjusted for inflation, according to a recent College Board report.

In a statement, Brown said his proposal would “extend ladders of opportunity to every Marylander, regardless of background or means.”

Brown faces Attorney General Douglas F. Gansler (D) and Del. Heather R. Mizeur (D-Montgomery) in the June Democratic primary. The Gansler and Mizeur campaigns declined to comment on Brown’s proposal.
