Meet the eligibility requirements. To enter the NBA Draft, you must be at least 19 years of age during the year of the draft, and at least one NBA season must have lapsed since your graduation from high school.
Express your interest in entering the draft in writing at least 60 days before the draft date. Include your name, state that you meet the eligibility requirements, and request a draft entry application form. Address the letter to Office of the General Counsel at the NBA offices in New York City.
Fill out and return the application form. The form requests personal information, proof of age from birth certificate or license, high school and college information, and agency representation, if any.
Check the Draft Express.com website and confirm that you are on the list about two weeks after submitting your application. If not, contact the NBA and check on the status of your application.
