• Teacher Liability Insurance (ELL) is designed to cover a wide range of non-personal injury/non-property liability claims against administrators, staff and employees of both schools and colleges. ELL, also known as School Board Liability Insurance, is a hybrid of traditional Principals and Officers (D&O) and Error and Omission (E&O) insurance. Typical claims covered by ELLs include wrongful termination, wrongful termination, failure to provide tenure, and negligent counseling.
