The problem with which this investigation is concerned is that of determining the influence of instructors' written comments on the test performances of students in selected college subjects. The students were from one university and one junior college. The written comments were designed to be positive in nature and to encourage better future test performances by students. The comments were made in regard to the letter grades received by the students and were placed only on major (as defined by each instructor) objective tests.

The primary purpose of the study was to determine the effectiveness of an intensive, in-service training program for modifying selected personality traits among para-professional counselor aides restricted to working with emotionally disturbed youth in a residential treatment center. Additionally, an attempt was made to identify the areas in which personality traits were modified, both between experimental and control groups and between males and females.
