| Abstract: | The introduction of electronic switching equipment has changed the nature of the telephone company switching job. A lengthy and complex training program must be completed before an employee can perform the electronic switching job. Because of the high cost of this training a more elaborate, second-stage selection procedure was developed. The ESS Minicourse was designed to be a self-paced content valid sample of ESS training which would be suitable for use with job candidates without any previous telephone company experience. A criterion-related validity study was undertaken to provide further evidence of validity as well as data helpful in setting a cutting score. Results showed that a combination of time to complete the Minicourse and performance on the objective tests was predictive of time to complete self-paced training in electronic switching. Cross- validated estimates of validity were used to develop estimates of u'tility given different selection ratios. |
