A letter of intent should be specifically targeted for each program you are applying to. It should be no longer than two pages, typed and single-spaced. The document should resemble a business letter, complete with your return address and contact information. When possible, the letter should address a specific person.
In the first paragraph, outline the program you are applying to, the degree you are seeking and why you are applying. Keep the tone professional and concise. Offer some sense of who you are and what you can offer. Your letter of intent will most likely be read along with your resume, transcripts, letters of recommendation and other information given in the admissions package. Put this information in context.
Broach goals within the first two paragraphs in your letter and reinforce them throughout the document. Your list should demonstrate knowledge of the program you are applying to. Assume that many similarly qualified candidates will apply to the graduate-school program. Showcase why your goals are significant and how enrollment in this program is essential to helping you reach them.
Incorporate your list of credentials throughout the document. If applying for a doctorate degree in psychology, note case studies you have been involved with or reports you have published that make you especially qualified for the program. Your letter should demonstrate an understanding of what the school and degree program offer; let your skills and accomplishments show why you would thrive in this program.
Your letter of intent is just that: a letter. Actual human beings will be reading it and reviewing it. Do not simply list your information and end the document. Offer a conclusion paragraph that sums up why you are a fit for this program. Thank readers for their time and consideration for having read your application; indicate that you look forward to hearing from the board.
