A Guide to Credit for Prior Learning
Typical Learning Experiences of Students Earning Lower-Level Credit:
- Attend training seminars, complete readings and/or have significant on-the-job experience in data communication.
Typical Learning Experiences of Students Earning Upper-Level Credit:
- Students generally earn lower-level credit in data communication. Those seeking upper-level credit often have significant experience in the design and/or analysis of complex data communication systems. For example, students may have designed LAN upgrades or coordinated the total install (hardware, software, configuration) of Wide Area Networks. Usually, a more specific title is given to reflect the aspect that makes the CBE an upper-level request.
If students are familiar with some (but not necessarily all) of the following topics, they may be eligible for lower-level credit in the area of data communication. If knowledge of some of the topics is substantial, the students may consider requesting additional credit in more narrowly defined areas.
