According to the National Center for Educational Statistics, more than 13 percent of public school children typically receive some type of federally funded special education, which illustrates the need for certified special education professionals. Numerous graduate schools offer special education diagnostician certification as a stand-alone program for certified teachers or as part of a master's degree.

Obtaining Diagnostician Certification

Applicants to special education diagnostician master's programs generally need a bachelor's degree, teaching certification and some teaching experience. If they only want the certification, they might need to have earned a master's degree, as required by the Texas State University program in San Marcos. The combination certificate and master's degree typically requires about 36 credit hours. Courses cover legal and ethical considerations in special needs instruction, as well as curriculum, instruction strategies and diagnostic methods and procedures. Other classes vary. For instance, Midwestern State University in Wichita Falls, Texas, offers an online program that includes coursework in educational research and a special education practicum. TSU says students looking just for certification should contact the school for a personalized program that may vary depending upon the applicant's background. Other schools, such as Texas Tech University, have a set program. Texas Tech's online offering for certification includes classes that focus on particular special populations in addition to testing and human development.
