On the front of a handout by our principal, I found these words in bold black print, "MORE IMPORTANT THAN CLASS SIZE." Immediately, I wondered what could possibly be more important than class size. Reading on I found that new research, concerned with the quality of our education system, had just been completed by Martin N. Olson, Executive Secretary of the Associated Public Schools Systems and a research associate with the Institute of Administrative Research (IAR). This one short article started me on a search for a copy of his study.
