Language scores are the standard scores from the Core Language Scale (receptive and expressive language) of the CELF-P2 (participants aged four years), and CELF-4 for other participants. Word and sentence intelligibility from the TOCS+ for participants aged 9;11 and under and from the SIT for participants 10;0 and older. CELF = Clinical Evaluation of Language Fundamentals; GMFCS = Gross Motor Functional Classification Scale; SIT = Speech Intelligibility Test; TOCS+ = Test of Children's Speech +.
