In the current era of accountability, tracking student achievement and success is of the utmost importance in higher education. While measuring student success may be particularly important to community colleges, it may also be especially complex in light of their multiple missions. This chapter discusses indices and other measures to gauge student success in developmental education programs. The authors discuss how community colleges can examine student success by presenting a measurement index. While the index may be usefully applied to any sequence of courses, they focus specifically on developmental education because so many community college students place into these courses and cannot progress or succeed in college-level work without remediating their academic skills deficiencies. In most colleges, students are not permitted to register for college-level English or math courses until they demonstrate college-level proficiency in these disciplines. (Contains 4 tables.)
