# failed inbde

Answer: After a failed INBDE you must wait at least 60 days, with a maximum of 4 administrations in any one-year period, and pass within 5 years of your first attempt or 5 attempts, whichever comes first. Past that limit the 2026 Candidate Guide (updated 08/04/2026) allows one attempt every 6 months — a change from the 2025 guide's 12 months, which is why older pages disagree. Every retake requires a full new application and fee: $890, plus $435 non-CODA processing ($1,325 for most internationally trained candidates). These restrictions are not subject to appeal.
