For the cohort test, we strongly recommend testing at least 200 students to obtain more precise measurement and to increase the likelihood that all of your demographic subgroups (major and class standing, for example) are sufficiently populated. A higher number (greater than 50) of students in each demographic or custom group will result in more precise measurement of that group and therefore more useful results. The absolute minimum required to close an administration is 50 students total.
Unless students are required to take SAILS as part of an institution-wide initiative, you will have to devise strategies for recruiting test takers. There are several avenues for recruitment.
Recruitment Scenarios
Faculty allow testing during class time
Provides access to larger groups of students at one time
May have more control over how representative the sample is
Encourages completion of the assessment by test takersFaculty encourage participation outside of class time by making it part of the class grade or offering extra credit
Ensures participation by majority of students
Encourages completion of the assessment by test takers
May have more control over how representative the sample isStudents self-select to take the assessment on their own time
May be difficult to ensure participation from enough test takers
Little control over how representative the sample is
Getting the Word Out
Working with faculty
Take advantage of any contacts you already have with faculty and department chairs. Faculty members who have shown an interest in having their students understand how to use the library may be willing to help gather information about students’ information literacy skills.Contacting students directly
Large numbers of students visit campus libraries every day, either in person or through library web pages. Announcements can appear on the home page, at service desks throughout the building, and be made in any library instructional sessions on campus.
