Data on students participating in transitional bilingual education programs (TBEs) in Massachusetts, in the 50 local education authorities (LEAs) with such programs, are reported and analyzed. Information presented, in graphic and narrative form, includes the following: an overview of the status of TBE programs in the state, including patterns of participation among eligible limited-English-speakers by language and enrollment trends since 1987; characteristics of secondary school TBE students who withdrew from their programs; characteristics of former TBE students who dropped out of school; post-graduation plans for public college attendance, private college attendance, military, work, and other pursuits, by language; years of participation, by language group; and program staff characteristics, functions, ratios, and certification status. Recommendations for further analysis of the data and for uses of that information are made. A list of the LEAs having TBEs is appended. (MSE)
