This booklet examines teachers' professional development from the standpoint of several recent reform reports, particularly the concept of the career ladder. A critique of this model serves as a reference point for an alternative approach to professional development called the "Career Lattice Model". This individualized model for growth in the teaching profession evolved from research on teacher career stages. The career lattice is a model that can provide financial, empowering, and personal incentives, and its flexibility provides options for teachers in various stages of their careers. It emphasizes collegiality, not competition, and can be used alone or as part of a career ladder or other career incentive plan. Examples are offered of the use of the career lattice model, and its strengths and limitations are pointed out. (JD)
