CBSE OSM Dashboard 2026: Principal Login & Teacher Mock Evaluation Rules
The Central Board of Secondary Education (CBSE) has officially launched a dedicated On-Screen Marking (OSM) Dashboard for school Principals and Head of Schools (HoS). This new digital portal is designed to facilitate and strictly monitor the mandatory mock evaluation process by all appointed teachers ahead of the CBSE Board Exams 2026.
Official Circular Issued — 21.02.2026
Authority: Central Board of Secondary Education (CBSE)
Reference: CBSE/H.Q./Coord./OSM/2026/ | Official Portal: cbseosm.onmark.co.in
The board has mandated that all teachers must log into the OSM portal and complete their mock evaluations. However, many teachers report missing their login credentials due to outdated contact details in the OASIS database. This new Principal Dashboard empowers school heads to manually trigger SMS/Email login credentials to their staff and verify their mock evaluation completion status in real-time.
Why do teachers need their OASIS data updated?
CBSE relies entirely on the OASIS platform to send the initial login IDs to the teachers’ registered email addresses and the mandatory One-Time Password (OTP) to their mobile numbers. If a teacher fails to receive the email, the Principal must ensure their exact email ID and mobile number are immediately corrected and updated via the OASIS application.
CBSE Evaluator Roles and Dashboard Indicators
When Principals log into the OSM Dashboard, they will see a comprehensive list of all appointed teachers from their institution. The system uses specific alphabetical indicators embedded in the User IDs to denote the exact evaluation role assigned to the staff member.
| User ID Indication | Official Designation | Action Required on Dashboard |
|---|---|---|
| ‘E’ | Evaluator | Monitor Log-in & Evaluation Status |
| ‘A’ | Additional Head Examiner (AHE) | Monitor Log-in & Evaluation Status |
| ‘H’ | Head Examiner (HE) | Monitor Log-in & Evaluation Status |
Can Principals resend the CBSE login credentials?
Yes. If an evaluator has not received the User ID and Password sent centrally by CBSE, the School Principal has the authority to directly push the login details to the concerned teacher by clicking the “Send SMS / Email” link available next to the teacher’s name on the scanning and evaluation dashboard.
How Principals Can Access the CBSE OSM Dashboard
- Visit the official CBSE OSM portal link provided in the circular: https://cbseosm.onmark.co.in/CBSE Dashboard/
- Enter the designated School User ID and Password.
- Authenticate the login using the OTP sent to the registered mobile number and email of the Principal.
- Select the active examination series (e.g., “Feb-2026”).
- Review the list of teachers under the “Scanning & Evaluation” section.
- Use the “View/Send Login Details” button to assist any teacher facing login difficulties.
What is the deadline for the mock evaluation?
While the circular dated February 21, 2026, focuses on immediate compliance, the mock evaluation must be completed urgently before the commencement of the actual live answer sheet evaluation process. Principals are strictly instructed to monitor the dashboard daily until the “Evaluation Status” for every assigned teacher marks as completed.

हिंदी सारांश
केंद्रीय माध्यमिक शिक्षा बोर्ड (CBSE) ने 2026 की बोर्ड परीक्षाओं से पहले शिक्षकों की मॉक इवैल्यूएशन (Mock Evaluation) प्रक्रिया को सुचारू बनाने के लिए स्कूलों के प्रधानाचार्यों हेतु एक नया OSM (On-Screen Marking) डैशबोर्ड लॉन्च किया है। यदि किसी शिक्षक को उनके पुराने ईमेल या मोबाइल नंबर के कारण लॉगिन आईडी और ओटीपी नहीं मिल रहा है, तो प्रधानाचार्य OASIS पोर्टल पर उनका डेटा अपडेट कर सकते हैं। इसके साथ ही, वे इस नए डैशबोर्ड के माध्यम से सीधे शिक्षकों को लॉगिन क्रेडेंशियल (SMS/Email) भेज सकते हैं और उनकी मूल्यांकन स्थिति पर नज़र रख सकते हैं।
