This paper describes the development of the Astronomy Diagnostic Test (ADT), a 33-question pencil-and-paper multiple-choice survey, up to the release of Version 2.0 in June 1999. The 21 content questions of the ADT (1) address concepts included in most introductory astronomy courses for non-science majors, (2) include only concepts recognizable to most high school graduates, (3) focus on one concept only, and (4) avoid jargon. Statistical analysis based on hundreds of students? responses, 30 open- ended written responses, and student interviews guided the wording and final selection of these questions.
