The first of two sections of this paper describes a pilot program that used interactive video (IAV) technology to enhance the scripting skills of teacher certification assessors in the administration of a classroom observation technique. A comparative analysis was drawn between three groups of assessors: those who received IAV programed instructional training, video only training, and no training at all. A pretest was administered to the first two groups; all three groups received posttests. No differences were found in the results for the three training methods, and this is attributed to the strong scripting skills already possessed by the assessors. The second section provides descriptions of each of the components of the IAV system used in the scripting practice study. The appendices contain examples of teacher certification criteria to be observed in the classroom, questionnaires used in the study, an example of a feedback screen, and a visual diagram of IAV components.
