Checked Oct 11, 2026. How every state compares
What these numbers do and do not show
- These are the 5 District of Columbia cases BadFaculty has verified so far, with outcomes dated 2004–2026. They are not a complete count of cases in District of Columbia.
- Records are added as public sources are found and checked, so totals reflect research coverage, not how often misconduct happens. Do not compare states, or years, by these counts.
- Only adjudicated outcomes appear: convictions and guilty or no-contest pleas in cases where a victim was a student. Arrests, charges and administrative license actions without a criminal outcome are not included.
- Each record links its sources. 5 of 5 cite a court record, prosecutor release or state board record. See the methodology.
Official sex offender registries
BadFaculty is not a sex offender registry, and the District of Columbia records on this page are not drawn from one. Many convictions involving school employees do not require registration, and registry status changes over time. For current registration information, use the official government sites.
- National Sex Offender Public Website (U.S. Department of Justice)
- District of Columbia official registry
- All state, territory and tribal registries
These are government websites. BadFaculty is not affiliated with them and does not copy, host or verify their data; their information can be incomplete or out of date, so confirm details with the agency that maintains the registry. Using registry information to threaten, intimidate or harass anyone, including registrants and their families, may be a crime.
