Some of California’s recent public school horror stories have clouded a previously clear picture regarding elementary class size reduction and its potential to enhance long-term student performance. ISM has previously expressed its viewpoint regarding the state of Tennessee’s remarkable Project STAR (Student-Teacher Achievement Ratio). Based on that project’s procedures and findings, we have for years routinely recommended class sizes of 13-17 in grades K-3. We have also emphasized the marketing advantages that can accrue to those private-independent schools that operate their K-3 programs within that range.
