Following the 1993 survey, we continued studying Tech Prep implementation, expanding our study to include quantitative and qualitative research methods. In 1995, we conducted a follow-up survey of the same group of consortia sampled in 1993 to determine how these local Tech Prep consortia had changed and/or progressed. In 1996 and 1997, we conducted in-depth field studies involving five local Tech Prep consortia located in different regions of the United States. This aspect of the research provided more detailed understanding of how Tech Prep implementation was advancing at the local level. To ensure readers have a clear understanding of the research methods used, we first present the procedures pertaining to our follow-up survey, then we review the qualitative, field study methodologies.
