ESR Has Transitioned to ClearStar
You have reached this web page because you attempted to access the Employment Screening Resources (ESR) website. ESR was acquired by ClearStar – a global Human Resources technology company specializing in background checks, drug testing, and occupational health screening – in December 2021 to be a “Service Offering of ClearStar.” The ESR website was maintained for a two-year “grace period” before being “sunset” in 2024. ClearStar offers outstanding client service, state-of-the-art technology, and vital compliance resources. If you would like to learn more about our services, are a client in need of support, or are an applicant for a job with a client who has a question, please contact us below!
