Here are some common types of qualification verification:

1. Direct Contact with Educational Institutions: This involves reaching out to the educational institutions mentioned by the candidate to verify the authenticity of the claimed qualifications. Contact can be made with the registrar’s office, admissions department, or designated authorities who can confirm the candidate’s educational background.
2. Document Authentication: Candidates may be asked to provide official documentation, such as degree certificates, transcripts, or diplomas. These documents can be verified for authenticity by checking for security features, seals, signatures, and other indicators.
3. Third-Party Verification Services: NVS enlists the services of third-party verification providers who specialize in qualification verification. 
4. Professional Accreditation Bodies: Certain professions require specific accreditation or licensing. Employers can contact the relevant professional associations or accreditation bodies to verify the credentials of candidates in those fields.
5. International Qualification Evaluation: When dealing with qualifications obtained from international institutions, employers can consult international qualification evaluation services. These services assess the equivalency of qualifications earned abroad and provide validation or conversion to the local educational system.
