Access Query

I have modified a Access 2007 template into a employee full detail log and added 21 specific training courses achieved,just need extra reporting tool installed to allow me to be able to produce a report by each employee and show what training certificates he is due for renewel in 3 months,and possible any other exception reports that could benefit my data. Already have a report available by training course,just need one to be able to select by employee,its probably simple query but i am bit tied up on other issues. Thanks
