The German professional development program SINUS was initiated 1998 in reaction to the disappointing German results in TIMSS. Since then, four SINUS-programs were conducted to enhance the quality of science and mathematics instruction by supporting teachers with a framework of modules to work on. In this chapter we describe a study of the last program SINUS for Primary Schools which compares mathematics competencies of fourth grade SINUS-Students with students in regular schools using TIMSS 2011 assessment. Findings show that SINUS students’ competencies are above TIMSS 2011 average in all mathematics content and cognitive domains. In addition SINUS shows a lower percentage of students on the lowest benchmark level. The findings need to be interpreted carefully because of the cross-sectional design of the study, but they corroborate the assumption that the SINUS-intervention has reached the student level, and that especially the weaker students have profited from the program. The findings correspond to former results of the SINUS study conducted in secondary school. All in all, the findings show the importance of programs aiming at teacher professionalization and instructional development.
