A New Aptitude Test

Your employer, C. Manufacturing Company (CMC), has just developed a new aptitude test. CMC believes it will accurately predict the future performance of new sales reps. (The company employees over 200 sales representatives and is planning to double this number next year, so this test is very important to the company.) The challenge is that it takes a new sales representative about 2 years to come up to speed on performance. For this discussion, describe how you could validate this new aptitude test so that meaningful data will be available after the first 50 new sales representatives are hired (in about 6 months). Why would you use this method for validating this test
