This report describes how California State University campuses apply the principles and methods of improvement science to the challenge of improving how the California State University System prepares teachers for K–12 schools.

The report explains the theory of improvement science and how approaches informed by improvement science differ from other improvement efforts.

The report then describes how the New Generation of Educators Initiative (NGEI) has put this theory into practice through providing technical assistance for NGEI grantees. Examples from the NGEI grantees are included to illustrate how improvement science principles have been applied in the teacher preparation context.
