The cost-effectiveness and impact on response rate of variations in mailing procedures involved in a mail survey of teacher education graduates were assessed. Variables studied were use of a preliminary or advance letter, postcard versus letter reminders as the first follow-up mailing, timing of the reminder (1 versus 2 weeks after the first mailing), use of a reminder versus no reminder prior to the mailing of the duplicate questionnaire, and timing of the mailing of duplicate questionnaires (3 versus 4 weeks following the first mailing when no reminder was sent). Subjects were 288 individuals who had completed teacher preparation programs leading to initial certification at a major institution in the Southeast from the fall quarter of 1987 through summer quarter of 1988; and 288 individuals identified through comparison of applications for certification, student teaching records, and graduation lists. Daily tabulations of returns for each experimental condition were maintained. Cost analyses covered outgoing postage; return postage; mailing labels for envelopes; letterhead stationary and envelopes; plain return envelopes; and duplication of letters, postcards, and questionnaires. Results indicate that the preliminary letters are not cost effective, while reminders and duplicate follow-up questionnaires are cost effective. Three tables and one figure are included. (TJH)
