Why the National Decline?Why the National Decline?

1. Loss of jobs due to mfg. moving offshore

2. Loss of local jobs due to economic conditions

3. Fewer technician jobs caused by improved technology

4. The societal Science, Technology, Engineering & Math (STEM) problem

5. Lack of understanding of what electronic technicians do

6. Lack of relevancy of college programs to local job needs

7. Outdated curriculum8. Faculty lack of

interest in and/or resistance to changing and updating programs
