This paper is an update and expansion of a 2003 AAPOR Conference paper "Achieving High Response Rates on Web-based Surveys of Post-secondary Students" (Nichols & Ghadialy). Using results from NORC's baseline, web-only survey of post-secondary minority students, the authors showed that Don Dillman's Tailored Design Method (TDM) (Dillman, 2000) was very effective in achieving high response rates on web-based surveys. In 2004, the first-follow-up survey in this longitudinal series was conducted by NORC. In this updated paper we will present how effective TDM was in increasing response rates by reviewing prompting efforts and survey results. We will look at the average number of contacts needed to yield one completed web survey, and discuss prompting innovations employed via mail, telephone and email to reach various population types to encourage their participation. When examining study outcomes, the paper will compare the demographic characteristics of respondents who responded in both the baseline survey and the first follow-up to those respondents who only participated in the baseline survey. Furthermore, we will present the sample attrition rate for the first follow-up study and compare these rates against other longitudinal surveys of post-secondary students.
