Delivering Well Prepared Teachers Policy
The state should ensure that special education teachers know the subject matter they are licensed to teach.
Nevada Administrative Code 391.343
Generic K-12 special
education licenses are inappropriate for teachers of high-incidence special
Too many states make no distinction between elementary and secondary special education teachers, certifying all such teachers under a generic K-12 special education license. While this broad umbrella may be appropriate for teachers of low-incidence special education students, such as those with severe cognitive disabilities, it is deeply problematic for high-incidence special education students, who are expected to learn grade-level content. And because the overwhelming majority of special education students are in the high-incidence category, the result is a fundamentally broken system.
It is virtually impossible and certainly impractical for states to ensure that a K-12 teacher knows all the subject matter he or she is expected to teach. Further, the issue is just as valid in terms of pedagogical knowledge. Teacher preparation and licensure for special education teachers must distinguish between elementary and secondary levels, as they do for general education. The current model does little to protect some of our most vulnerable students.
Special education teachers teach content and therefore must know content.
While special educators should be valued for their critical role in working with students with disabilities and special needs, the state identifies them not as "special education assistants" but as "special education teachers," presumably because it expects them to provide instruction. Inclusion models, where special education students receive instruction from a general education teacher paired with a special education teacher to provide instructional support, do not mitigate the need for special education teachers to know content. Providing instruction to children who have special needs requires knowledge of both effective learning strategies and the subject matter at hand. Failure to ensure that teachers are well trained in content areas deprives special education students of the opportunity to reach their academic potential.
Special Education Teacher Preparation: Supporting Research
For an analysis of the importance of special educator content knowledge see N. Levenson, "Something Has Got to Change: Rethinking Special Education", American Enterprise Institute, Future of American Education Project, Working Paper, 2011-01.

Numerous research studies have established the strong relationship between teachers' vocabulary (a proxy for being broadly educated) and student achievement. For example: A.J. Wayne and P. Youngs, "Teacher characteristics and student achievement gains: A review," Review of Educational Research, Volume 73, No. 1, Spring 2003, pp. 89-122. See also G.J. Whitehurst, "Scientifically based research on teacher quality: Research on teacher preparation and professional development," presented at the 2002 White House Conference on Preparing Tomorrow's Teachers; R. Ehrenberg and D. Brewer, "Did Teachers' Verbal Ability and Race Matter in the 1960s? Coleman Revisited," Economics of Education Review, Volume 14, No. 1, March 1995, pp. 1-21.
Research also connects individual content knowledge with increased reading comprehension, making the capacity of the teacher to infuse all instruction with content of particular importance for student achievement. See D.T. Willingham, "How knowledge helps: It speeds and strengthens reading comprehension, learning—and thinking," American Educator, Volume 30, No. 1, Spring 2006.

Sandra Stotsky has documented the fact that teacher candidates often make inappropriate or irrelevant coursework choices that nonetheless satisfy state requirements. See S. Stotsky with L. Haverty, "Can a State Department of Education Increase Teacher Quality? Lessons Learned in Massachusetts," in Brookings Papers on Education Policy: 2004, ed. Diane Ravitch (Washington, D.C.: Brookings Institution Press, 2004).
On the need for colleges and universities to improve their general education coursework requirements, see The Hollow Core: Failure of the General Education Curriculum (Washington, D.C.: American Council of Trustees and Alumni, 2004). For a subject-specific example of institutions' failure to deliver solid liberal arts preparation see, The Coming Crisis in Citizenship: Higher Education's Failure to Teach America's History and Institutions (Wilmington, DE: Intercollegiate Studies Institute, 2006).
For information on teacher licensing tests, see The Academic Quality of Prospective Teachers: The Impact of Admissions and Licensure Testing (Princeton, NJ: Educational Testing Service, 1999). A study by C. Clotfelter, H. Ladd, and J.Vigdor of elementary teachers in North Carolina also found that teachers with test scores one standard deviation above the mean on the Elementary Education Test as well as a test of content was associated with increased student achievement of 0.011 to 0.015 standard deviations.
