Letters of Recommendation

Three letters of recommendation are required to complete your application for admission. Letters of recommendation may comment on either your academic and employment background, but letter writers should be qualified to evaluate the quality of your scholastic achievements and academic training as well as your ability to carry out independent research. This is especially important if you have previous research experience. One character or personal recommendation is permissible. It is helpful to tell your references to address those characteristics that are important to your admission. All letters are to be submitted through Embark Online Recommendation. Please do not send letters through Interfolio. UC Davis will not accept letters sent on paper.
