This paper presents a descriptive model of the subject matter taught in courses on expert search in ALA-accredited programs, answering the question: What is taught in formal professional education on search expertise? The model emerged from a grounded content analysis of 44 course descriptions and 16 syllabi, and was validated via a review of literature on search instruction. The model provides a framework for further research on the pedagogy of professional search education, and its role in the development of search expertise.
