What was Armstrong vs kline?

n Armstrong v. Kline (1979), the parents of five students with severe disabilities claimed that their children tended to regress during the usual breaks in the school year and called on the schools to provide a period of instruction longer than 180 days. The court agreed and ordered the schools to extend the school year for these students. Several states and local districts now provide year-round educational programs for some students with disabilities, but there are no clear and universally accepted guidelines as to which students are entitled to free public education for a longer-than-usual school year.
