The first section of the update lists responses received to date to a survey of teacher portfolio use. Fourteen preservice and inservice teacher education programs and 12 kindergarten through grade 12 school districts responded with brief descriptions of their portfolio use and with contacts and addresses for further information. The second section is an annotated bibliography of four studies on teacher portfolios published since November 1991. A final section reviews the state of the art in teacher portfolios. Several teacher education programs that responded appear to use portfolios as a means of increasing teacher reflection and providing a record of teacher growth to be discussed and shared with other teachers. The remainder appear to be using teacher-constructed portfolios to increase the quality and specificity of the assessment process. Some schools districts are using teacher portfolios as a way for teachers to demonstrate professional growth. A few are using or considering portfolios as part of the teacher certification system. This path seems premature, based on the experience with teacher portfolios so far. The promise of portfolios remains bright, but remaining concerns must be addressed before the relationship between the portfolio and its content and scoring can be reliably defined. (SLD)
