The problem of this study was to determine the effect of academic self-concept, student aspiration, intellectual achievement responsibility, and certain other personal factors on the attendance patterns of selected ninth grade students, and to develop from data on all factors a typical profile of conditions likely to result in high absenteeism and make recommendations for initial steps in remediation. As a result of the statistical analysis and subsequent retention or rejection of the null hypotheses, the significant findings of this study may be summarized as follows. (1) Ninth grade attenders are significantly younger than non-attenders. (2) Attenders had more siblings than non-attenders. (3) Attenders are significantly more involved in school organizations than non-attenders. (4) There is a higher frequency in suspensions among non-attenders. Based on analysis of the findings of this study and within the limitations of the population described in the procedure section, the following conclusions were formulated. (1) Students who have been retained, started school later, or for some reason are older than their classmates, are more likely to attend school irregularly.(2) Educators cannot expect to find the major causes of student absenteeism to be academic self-concept, intellectual achievement responsibility, or student aspiration. (3) Family size may be an important consideration for educators to investigate when working with school non-attenders. (4) School attenders can be expected to be actively involved in the co-curricular elements of the school program. (5) Higher rates of student suspensions are more likely to increase attendance problems rather than reduce them. (6) How students use their time outside the school day is not likely to be the crucial factor in school attendance. (7) While students often complain about schedules, teacher selection, and proximity of friends, it is not likely that changes in these factors would influence student attendance.
