A school board must be cautious in adopting a policy for nonrenewal of teachers whose performance is unsatisfactory. The author of this third chapter of a book on school law suggests a policy that supports the board's ability to retain the best teachers and weed out mediocre teachers without violating a teacher's rights. Before adopting the policy, a board should determine whether any part of the model conflicts with state statutes or the district's collective bargaining agreement. Moreover, a competent understanding of constitutional law, as relevant to termination of public employees, is necessary in considering such adoption. The author's suggested policy delineates permissible and impermissible grounds for nonreappointment. It also includes procedures to follow in delivering a notice of nonrenewal, requesting and conducting a conference, requesting to appear before the board, responding to such a request, and conducting a hearing.
