Ed Walker and Bobby Knight were part of the Chuck Geiger School of Programming at WCTO Allentown., They were being trained as internal candidates to program elsewhere in Citadel. Ed went to WHWK Binghampton and Bobby to WLEV in the building. Bobby and I actually numbered and labeled sequences of events that came up and how you would deal with them. From sales to staffing issues to missing spots to the afternoon guy whining to the business manager about the programming team. I don't think the internal applicants these days are part of any training or fostering program. They are just there and the bean counters figure: We don't have to pay relocation, we don't have to pay the salary of the last PD, plus they don't have their own agenda. They are trainable like a pet seal in a show.
At The Fresno Bee - We have a "purple sheet" you fill out for a position that is open (for internal applicants). They have a great system for monitoring the process. I could be all wrong and wet behind the ear, but I never heard of internal applicants for jobs in radio programming, unless they are assistant programmers, and yet they are everywhere. This information below is pretty helpful when it comes to nailing this down.
