this is way to broad a question. we have no idea how you are saving their training information. Personally I have created a very complicated workbook that tracks the current revision of the training materials, the training requirements for each individual, and then has what I call 'soft passwords' for each individual so they can 'log in' and then it generates a training matrix specific for them and admin login that lets them update/edit specific items (it only requires macros for the admin login not the 'soft login' for the individuals). But in your case if everyone has the same training requirements and all in the same table then maybe a simple filter on the table?
