What exactly is an "academic plan"?
I suspect that even if the TERM is not defined, that knowing the JOB will help you make a proper submission.  Is it a postdoc or lecutureship or tenure track? Even if the job description is scanty (but why would you invest time in a detailed submission for a job that you don't know what it is), you can make some guesses based on the school, group, etc.  Is the school a teaching or research university? 

So, I really don't understand coming at this thing with a "can you explain this term to me" versus giving more context, clues.  This is both you might answer the question yourself or how we might help you.

Also, I would reach out say you are interested and ask for guidance.
