WBCHSE to Introduce UV Security Threads in HS Marksheets

MP, KOLKATA, JAN 10, 2026: The West Bengal Council of Higher Secondary Education (WBCHSE) will embed ultraviolet (UV) security threads in Higher Secondary (HS) marksheets and pass certificates to prevent forgery, officials said.

The UV threads, invisible to the naked eye, can be detected only under UV light. WBCHSE president Chiranjib Bhattacharya stated that multiple micro-threads will be used instead of a single strip, making duplication and tampering extremely difficult. “These can be seen only under a UV lamp or torch. The purpose is to prevent forgery, similar to the security features used in currency notes,” he said.

The new security feature will be incorporated in final consolidated marksheets and pass certificates issued after Semester IV examinations, while the existing QR code-based verification system will continue.

This decision follows detection of forged HS marksheets, prompting the Council to strengthen document security. Under the semester system, Semester III marks were issued online with printed copies provided by schools, and the final consolidated HS marksheet will include marks from Semesters III and IV, supplementary, practical, and project marks, along with percentile scores and grades.

The WBCHSE had earlier introduced other security measures such as unique serial numbers on question papers embedded in QR codes and barcodes, which candidates were required to write on their answer sheets.
