Ask the applicant if there are any specific items that they would like you to address in your letter. Applicants should be prepared to show you copies of their statements, transcripts, and other relevant material (such as their list of awards, honors, publications and presentations from their application, their CV, etc.). Many compelling applications include components that work well together – the information is consistent without being repetitive; each component offers different information about the applicant as a researcher and a person. Taken as a whole, the entire package demonstrates how well the applicant meets the Merit Review Criteria. For example, the information in your reference letter might provide details to support and elaborate upon information the applicant included in her or his statements.
