This research aims to determine the opinions of prospective classroom teachers about preparation and implementation of Individualized Education Program (IEP). In this study, a qualitative research method was used. The participants were 20 classroom-teaching students that had been selected through the purposive sampling method. In the study, the questionnaire "Examining IEP" was used as a reference, which has been improved by the researcher. The questionnaire includes open-ended questions. According to the analysis results, prospective class teachers state that they do not think that they are qualified enough to evaluate students' performance, to identify individual needs which is related to the performance, to set or create goals, to collaborate with parents and school administration, or to plan educational adaptations. They also state that they have concerns about possible problems that may arise during implementation of individualized education programs.
