Work Keys provides a metric that translates skill requirements for individual jobs into levels of proficiency. It has been developed as a multifunctional program with the interactive components of Job Profiling, Instructional Support, Reporting, and Assessment. The assessment component contains applied mathematics, applied technology, teamwork, and observation aspects. The American College Testing (ACT) program furnishes supplies for the Work Keys program and provides computer scoring. The system is a generally well-developed and well-executed product. When used effectively it can assist companies with employee selection and aid students in the smooth transition from school to work. Work Keys assessments are not norm-referenced, but a norming sample was drawn using 14,584 individuals to evaluate internal consistency. Research has also supported the validity of Work Keys. The ACT adheres to high standards in Work Keys and provides extensive client services, but budget restraints might hinder organizations in fully implementing the Work Keys System. Some limitations to the use of Work Keys are identified, but it is concluded that it provides individuals with career planning information regarding existing skill levels and levels needed to perform the jobs they want.
