The report describes a sample of effective vocational assessment practices for handicapped students implemented in California. An introduction presents the challenges and difficulties of complying with federal and state legislation that mandate nondiscriminatory vocational assessment and the least restrictive placement. Alternatives to standardized vocational testing are considered (such as work samples and job performance assessments). Common practices are cited regarding assessment instruments, examiner expertise, and coordination of services. Potential improvements are also pointed out. Six projects are described in terms of critical issues, implementation/maintenance, outcomes, resources required (staff, equipment, training, and funds), and suggestions for improvement. Practices address such areas as job performance assessment, criterion referenced assessment, use of paraprofessionals to conduct assessments, and coordination of services between a department of rehabilitation and a school district's department of special education.
