Teacher socialization begins much earlier than the moment the novice teacher enters the classroom for the first time. Contemporary theory suggests that this socialization may begin in infancy or early childhood and progress through the preservice teacher education experience. In order to observe the effects of the school environment on novice teachers, baseline data must be obtained from them between the time they complete their preservice training and the time they begin their professional activities. This paper describes a profile data collection instrument designed to gather the baseline data (information about the novice teacher's demographic and socioeconomic status, factors influencing the career decision, professional activities during preservice teaching, teaching experience before beginning in-service work, perceived importance of professional sources of knowledge, and confidence in teaching abilities). A copy of the profile instrument is attached. (JD)
