How can I effectively write a draft letter of recommendation?

To write an effective draft letter of recommendation, start by introducing yourself and your relationship to the person you are recommending. Then, highlight the person's strengths, skills, and accomplishments relevant to the position or opportunity they are applying for. Provide specific examples and anecdotes to support your claims. End the letter with a strong, positive conclusion and offer to provide further information if needed. Be sure to proofread the letter for clarity and accuracy before sending it.
