The purpose of the present study was to examine the potential that parents could effectively administer an online dyslexia evaluation tool (ODET) to their children. To this end, four groups consisting of parents and trained staff were compared. Sixty-three children (36 females and 27 males) participated. The children in each group were assessed twice. In the Parent-Parent group, children were assessed at Time 1 and 2 by their parents, in the Parent-Professional group children were assessed at Time 1 by their parents and Time 2 by trained staff, in the Professional-Parent group children were assessed at Time 1 by trained staff and Time 2 by their parents and in the Professional-Professional group, children were assessed at Time 1 and Time 2 by trained staff. The results indicated that parents performed nearly identically to trained professionals, suggesting that parents could reliably administer the ODET.
