Legal questions relating to secondary education continue to be prolific. Two influences principally affect this situation, namely: (1) the dynamic and progressive nature of education; and (2) vague and chaotic conditions of laws affecting secondary schools. With respect to the first of these influences, no valid objections or modifications have been urged (except, perhaps, that education has not been dynamic enough). The second influence challenges the attention of school administrators, legislators, and other friends of education. The purpose of this monograph has been to study in a comprehensive way the principal statutory and regulatory provisions which affect the organizations and standards of secondary education in the United States. The standards prescribed by educational institutions within the respective States and by regional accrediting associations have also been included in this study. These latter standards, while not having the authority of law, are regarded as exercising indirectly sufficient influence on secondary education to warrant attention in a study of this kind. It is hoped that the study may afford a basis not only for comparison but also possible evaluations of varying types and degrees of present legal and regulatory control of secondary schools in the light of current professional opinion. The principal sources of data for this study are: (1) State constitutions; (2) State codes and session laws; (3) State school-law manuals; (4) State supreme court reports; (5) regulations and regulatory standards in publications of State departments of education; (6) standards required by regional accrediting associations; and (7) previous earlier related studies. This bulletin is divided into seven chapters, as follows: (1) Purpose and Background; (2) Local Organization for Control of Secondary Schools; (3) Grades of Secondary Education; (4) Compulsory School Attendance, Tuition, and Transportation; (5) State Administrative and Supervisory Control; (6) Regional Accrediting Associations; and (7) Conclusions.
