教育诊断学家是特殊的教育专业人员，他们评估和诊断有学习困难的孩子。要获得教育诊断师认证，您必须具有硕士学位，成功完成33个学期的教育诊断师认证，并通过必需的TExES考试。可以与特殊教育硕士学位一起获得此认证，并且某些课程可以同时达到这两个目标。
The Master's in Special Education prepares educators for initial teaching certification and/or educational diagnostician certification. Members of this program gain advanced expertise in culturally and linguistically responsive special education services to students with both high-incidence and low-incidence disabilities. Theory and pedagogy from English learner education and special education are combined. Educational diagnosticians are special education professionals who assess and diagnose children with learning difficulties. To be certified as an educational diagnostician, you must have a master's degree, successfully complete the 33 semester hours for Educational Diagnostician Certification, and pass the required TExES exam. This certification may be earned in conjunction with the Master's Degree in Special Education, and some classes count toward both objectives. The Educational Diagnostician certification program can be taken concurrently with the MS Special Education degree program or alone by a certified teacher who has a graduate degree. This coursework prepares students to assess, diagnose, and support instructional planning for students referred to special education.
