Defining the Test’s Purpose Test development begins with a clear statement of purpose: usually just one sentence o What trait are you trying to measure? Focus on scores to be given and type of interpretation intended o Who is the target audience? Once defined, does an appropriate test already exist? o Use sources of information outlined in chapter 2 2. Preliminary Design Issues Several issues to consider: o Mode of administration (individual vs. group) o Length (short limits reliability, or long more reliable) o Item format (M/C, T/F, Likert scale, etc.) o Number of scores o Score reports o Administrator training (how much is necessary?) o Background research in the area (lit research, discussions with practitioners, etc.)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
