The recent passage of legislation in California requiring local education agencies to establish performance based education programs will increase the role and responsibilities of school librarians and media specialists. The legislation will result in giving librarians, through the goals established by the school district, specific objectives in which they must focus their energies. Areas identified in which they can enhance performance based programs include: (1) suggesting and evaluating educational alternatives that will better accommodate the needs of certain students who are unable to meet criterion standards; (2) informing parents of the proficiency standards by which their children will be evaluated and expected to achieve; (3) serving as resource agents to the teaching staff in coordinating the combined resources of the school and community in meeting individual pupil needs; (4) helping the teaching staff in developing pupil assessments; and (5) assisting in the development of individual objectives and goal statements. School districts who make full utilization of their librarians will find a wealth of resources waiting to be tapped; effectively used, school librarians can serve in one of the most important support roles in the assessment process.
