This document defines invitational teachers as those special teachers who have the ability to invite their students to achieve. Invitational teachers hold positive perceptions about themselves and see students as able, valuable, and capable. The major problem associated with employing more invitational teachers has been one of identification; this study tested a set of self-instructional materials which would supply teacher selection officials with the skills necessary to make accurate assessment of perceptual orientations for use in teacher selection. The results indicate that teacher selection officials can be trained to use perceptual inference data in making teacher selection decisions. The self-instructional material developed provided selection officials with a high degree of inference skill. A second conclusion was that the ability to make reliable perceptual evaluations depends to some degree on the perceptual orientation of the person making the evaluation. (Author/JD)
