There are several national, standardized test out there (e.g. ASSET) who could help you determine if students need specific help in certain basic academic areas such as math, reading, writing, etc.
Additionally, there some some web-based assessments that help students determine their 'readiness' for school by measuring their computer literacy, time management, etc. READi is one of those. Here's their link http://www.readi.info/
