Analysis comparing ISAT gains (spring 2006 to spring 2007) for elementary schools and PLAN-to-ACT gains for eleventh-grade students in cluster versus non-cluster schools, controlling for student and school characteristics. Only one year of comparable data available.
"There were no significant differences in one-year learning gains between schools with clusters of NBCTs and similar schools with similar students."
