in 1953. The parents had begun the program in 1950, using whatever space could be found to educate their children, but eventually asked FCPS to take control of the program. Special education classes for mentally disabled students were expanded in 1955 to four classes for "educable" (those with a mental age above 7) children at Groveton, Lincolnia, Oakton, and Luther Jackson schools, and a class for "trainable" (those with a mental age of less than ) children at Groveton. Debate over grading policy Fairfax County Public Schools was known for using a 6-point grading scale. Before May 7, 2009, 94–100% received an A, 90–93% was a B+, 84–89% was a B, and so on. In 2008, a parent group raised concerns about whether the FCPS method of computing grades and applying weights for advanced courses adversely affected FCPS applicants for college admissions, honors program placements, and merit-based scholarship awards. On January 2, 2009, Superintendent Jack D. Dale announced his decision on the issue, recommending changing the weights of advanced courses but maintaining the six-point grading scale. Dale stated there was no conclusive evidence the six-point grading scale is disadvantageous for the students of FCPS. Fairfax County Public Schools worked with the parent group to conduct a joint investigation into the issue. On January 22, 2009, the FCPS School Board directed Superintendent Dale to report to it with a new version of the grading scale by March 2009. The board also approved changing the weighting for Honors to 0.5 effective with the 2009–2010 school year and for AP and IB courses to 1.0 retroactively. After investigation, the Fairfax County School Board approved a modified ten-point scale with pluses and minuses. The new scale went into effect at the beginning of the 2009–10 school year. 93–100% is an A, 90–92% is an A−, 87–89% is a B+, and so on. Controversy over disciplinary policies Fairfax County Public Schools' disciplinary policies for drug offenses came under community scrutiny in 2009 after two students committed suicide after being subject to school disciplinary proceedings. Both 17-year-old Josh Anderson of South Lakes High School, who died in 2009, and 15-year-old Nick Stuban of W.T. Woodson High School, who died in 2011, had been suspended from their schools for marijuana-related offenses. The school district also suspended at least one student for possession of her prescription medication. Although then-Superintendent Jack D. Dale maintained that the disciplinary policy did
