Validity Generalization My only experiences with police officer selection revolve around a city in Ohio during the 1970s. The city was a small, affluent suburb of Cleveland. It had hired two of my mentors to develop, test, and then possibly implement a selection system for police officers. As Ph.D. students, we were cheap but relatively competent labor for these two mentors. Developing selection systems is a time consuming, stressful process. But for a well-trained selection consultant, it can be a highly lucrative business. As our team considered options for helping the small, affluent city, we discussed borrowing a selection system from Cleveland, Ohio. This would have been tantamount to using Validity Generalization. There are many people who have argued that the situational specificity hypothesis of validity has not demonstrated any real value to the profession. Your assignment (worth a possible 50 points is two-fold. First, using the book, the Phillips Supplement, and other readily available resources, clearly define the two related concepts of the situational hypothesis of validity and validity generalization. The Glossary in the book might be a really useful place to start. But glossary definitions are not always sufficient for being considered thorough definitions. Then, as a selection expert, tell me whether you would have been willing to generalize the validity of a selection system that had been used successfully in a large, economically diverse city such as Cleveland to the small, affluent, relatively homogenous suburb that had hired my mentors. Here is a template for organizing your submission: Number 3 can be handled in no more than one page. 1. The situational specificity hypothesis of validity can be defined as: 2. The definition of validity generalization is: 3. As a selection expert, I would/would not (choose one) have been willing to generalize the validity of the selection system that had been developed and used in Cleveland, Ohio to the small, affluent suburb. Here are my explanations and justifications for this answer:
