In 2019, a dispute about the use of Spelling to Communicate (S2C), a brand of RPM, developed between the Lower Merion School District and the parent of a child attending school there. The parents claimed the child was deprived of a free education because the district declined to pay for a private educational program based on S2C. In December of that year, the found that there was no evidence that S2C enabled the child to communicate and thus the school district prevailed.
