On May 27th, 2021 the Suffolk County Police Department Applicant Investigation Section will send, via US mail and email, invitations and important documents related to upcoming police candidate orientations. These invitations will be sent to candidates on the Open Competitive Police Officer list who received a score of either 105, 100 or 95 lottery number between one and 1250 as well as candidates on the Open Competitive Police Officer (Spanish speaking) list who received a score of either 105, 100 or 95 lottery number between one and 428. Some candidates who were previously invited to the police candidate orientation may be ineligible to be invited again.  If you believe you did not receive an invite but should have, contact the Applicant Investigation Section at 631-852-6203.
