DES MOINES, Iowa (AP) — Gov. Terry Branstad and Iowa lawmakers have invested plenty of time on proposed reforms to Iowa’s public schools, but it looks like big changes to the education system are unlikely this session. Branstad initially offered a number of proposals, including linking teacher pay to performance in the classroom, requiring potential teachers to meet grade point standards before they could seek education training and holding students back if they didn’t meet reading benchmarks. After complaints from teacher groups and others, Branstad delayed the proposed salary changes, and now it appears that many of his other proposals will fall by the wayside due to disagreements with Senate Democrats. Senate Majority Leader Michael Gronstal notes the Legislature likely will approve plans to increase spending on early elementary programs.
