This report describes the organization of selected Illinois English and education teachers and scholars who cooperated in a 5-year research project to develop an "ideal" plan for teacher preparation in English, to discover through experimentation how these recommendations for improvement could be utilized in diverse institutions, and to evaluate changes which resulted from these recommendations. The document states (1) ISCPET's background and objectives, (2) its administrative structure, (3) results of ISCPET's activities, e.g., the special studies it commissioned, the "self-studies" of cooperating institutions, and the impact of the project on the national scene, and (4) ISCPET's conclusions and recommendations for reforms in English teacher preparation. Detailed summaries of ISCPET's 33 special studies on teacher preparation, evaluation, and improvement are presented. A preliminary and final statement on qualifications of secondary school teachers of English, a summary of ISCPET's activities, a list of its publications, and ISCPET's six Illinois Teacher Rating Scales are appended.
