The parallels between reading and spelling skills in Arabic were tested. One-hundred forty-three native Arab students, with typical reading development, from second, fourth, and sixth grades were tested with reading, spelling and orthographic decision tasks. The results indicated a full parallel between the reading and spelling performances within the second and fourth graders where the performance in the orthographic decision task was significantly lag behind. For the sixth graders, full parallel was found between the spelling and the orthographic decision performances with significant superiority of both performances on the reading performance. The results were discussed in light of developmental course of the orthographic representations and the impact of the specific orthographic features of the Arabic orthography on reading and spelling.
