Grateful acknowledgment is due the principals of each of the high
schools whose records are included in this study, for the courteous and
helpful attitude which they and their assistants manifested in the work
of securing the data. Thanks are due Dr. John S. Tildsley for his
generous permission to consult the records in each or any of the New
York City high schools. But the fullest appreciation is felt and
acknowledged for the ready criticism and encouragement received from
Professor Thomas H. Briggs and Professor George D. Strayer at each
stage from the inception to the completion of this study.
