This study compared students with specific learning disorders (SLDs) and attention-deficit/hyperactivity disorder (ADHD) based on the Formal Elements Art Therapy Scale (FEATS). Thirty students with SLDs, 30 students with ADHD, and 30 students without SLDs/ADHD in Babol (Iran) completed the Person Picking an Apple from a Tree (PPAT) assessment. Findings revealed: (1) a significant difference between the SLD and non-SLD/ADHD groups in all elements, except for logic and rotation, (2) a significant difference between the ADHD and non-SLD/ADHD groups in all 14 elements of the scale. The inter-rater scoring correlation was significant and high in 14 elements of the scale, except for realism and person. Accordingly, the PPAT shows potential for application in preliminary identification and on-going evaluation.
