We investigated how high school mathematics course placement contributes to inequalities in college preparation for students categorized as "English Learners" (ELs), especially "long-term" English Learners (LTELs). We devised a base-2 enumeration approach that allowed us to process complex transcript data from one school…

Researchers are concerned that English language learners (ELL) may remain classified too long and, therefore, may not receive appropriate mainstream educational services.

Students are non-randomly assigned, or sorted, into classrooms in various ways across and within schools.

We analyze whether non-random student assignment is associated with value-added estimates for…

The focus of this study was on increasing the knowledge base on students with disabilities at the secondary level. Data were gathered on 559 classified secondary students with disabilities served in four educational options: cotaught classes, resource rooms, alternate day support programs, and no direct supports. Results indicate that there are…

The federal government's Race to the Top competition has promoted the adoption of test-based performance measures as a component of teacher evaluations throughout many states, but the validity of these measures has been controversial among researchers and widely contested by teachers' unions. A key concern is the extent to which nonrandom sorting…
