Problems with assessment

I am currently teaching at a secondary school. I am in 2 departments - Science & Technology. It has become very apparent to me the vast differences in ways of assessment in these 2 departments - 1, Technology, being completely internally assessed - based on observations, resits offered, conferencing entered into, quality of workmanship - the other a combination of both - internally assessed with 1 resit offered & end of year exams. My issue is how can a school formulate an assessment policy that covers these very vast differences in assessment?
What do you think?
