A former Abbotsleigh student has lost her appeal against a decision by the NSW Board of Studies not to grant her special examination provisions in the form of a computer and extra exam time for the 2008 Higher School Certificate.

Sarah Hui Xin Wong took the Board of Studies to the Administrative Appeals Tribunal claiming she was unlawfully discriminated against on the ground of disability.

Ms Wong, now 21, says the board failed to adequately accommodate her joint hyper mobility of the wrist and hand during her English Advanced and Modern History exams.

Ms Wong was granted rest breaks during the exams. She was also offered the use of a writer, who would take down her dictation. However, she chose not to use this option.

Ms Wong scored a university entry rank of 99.95 and is studying medicine at the University of Sydney. She came fifth in the HSC Chemistry exam when she was in year 11, in 2007.
