What Worked Last Year May Not Work This Year

October 2026. Your data entry operator follows the same process they used in 2025-26. Same sections, same order, same fields. They submit. The BRC rejects — not everything, but three specific things: APAAR IDs are not complete for 67 students (the system issued a warning last year, but blocks certification this year), the WASH section has blank sub-questions the operator did not see (new this year, which the portal does not import from 2025-26), and the digital infrastructure section shows validation errors for fields that did not exist in last year's form.

These are not random problems. They are predictable consequences of changes that the developers made to the UDISE+ system between 2025-26 and 2026-27. Schools that know what changed can prepare before they open the portal. Schools that assume this year is the same as last year will find out what changed only when the BRC sends their data back.

This page covers the 5 specific changes in UDISE+ 2026-27 that will trip up schools operating on last year's workflow.

Change 1: APAAR Now Blocks Certification — Not Just a Warning

In 2024-25, the portal made the APAAR ID optional. In 2025-26, the portal flagged incomplete APAAR as a warning but schools could still certify their data. In 2026-27, the APAAR ID blocks certification — schools cannot complete data certification at the block level if students have missing APAAR IDs.

What this means in practice:

• Any student without an APAAR ID will prevent you from fully certifying the SDMS module — the system will not just flag it
• You must generate APAAR IDs for students who attended your school last year but whose APAAR you never generated (due to absence during authentication, Aadhaar mismatch, or lack of Aadhaar) before you can submit this year
• You must collect Aadhaar cards and generate APAAR IDs for all Class 1 new admissions before the submission deadline — do not leave this step for "later"

What to do immediately: Pull the list of students from SDMS whose APAAR field is blank. Sort by class. Contact the families of those students and collect Aadhaar cards this week. APAAR generation for 50 students with Aadhaar cards in hand takes about 3-4 hours. Without the Aadhaar cards, it takes 3-4 weeks.

Change 2: WASH Section Has New Sub-Questions That Default to Blank

The School Profile WASH (Water, Sanitation, Hygiene) section in 2026-27 contains more sub-questions than in 2025-26. The portal does not carry these new fields forward from last year's data — they appear as blank, which means your WASH section remains incomplete even if you filled it completely last year.

The new sub-questions include:

• Toilet type classification: Flush/pour flush, pit latrine, or dry toilet — previously "number of toilets" was sufficient
• Functional status as of September 30: The portal now splits the toilet count into "existing" and "functional" — you must count a toilet that exists but is broken under "existing" but not under "functional"
• Hand-washing facility location: Whether you place the hand-washing facility adjacent to toilets or only in the kitchen/classroom area
• Water testing status: Whether you tested the school's drinking water in the current year

To fill these accurately: physically walk through the toilets and water facilities before opening the portal. Count how many toilets are actually working on September 30. Check whether you conducted any water test. Enter what you physically verify, not what looks reasonable from memory.

Change 3: Digital Infrastructure — New Fields Schools Are Missing

The School Profile's infrastructure section in 2026-27 includes new fields for digital facilities that were not in the 2025-26 form:

You must physically verify each of these before entry. Do not estimate or copy from grant application records — what you applied for and what actually exists may differ.

Change 4: Teacher Module Aadhaar Verification Is Stricter

PEN generation in the Teacher Module has always required Aadhaar authentication. In 2026-27, the portal has tightened the name and date of birth verification against Aadhaar — mismatches that passed in 2025-26 may now fail.

Specifically:

• Name format: The teacher's name in SDMS must match the Aadhaar format exactly — including middle names and initials. "Ram Prasad" in SDMS may fail if Aadhaar says "Ram Prasad Sharma."
• DOB format: Teachers who had only birth year in Aadhaar (no exact date) may find that the 01/01/YYYY convention no longer passes Aadhaar authentication in all states.
• Training categories: New training types that the developers added this year (DIKSHA courses, FLN training) must use the new dropdown values — old free-text entries in qualification fields may fail validation.

Before you generate or update teacher PENs: check each teacher's physical Aadhaar card against their Teacher Module entry. Any discrepancy will cause an authentication failure that takes multiple BRC contacts to resolve.

Change 5: Validation Is Tighter — Old Data May Now Fail

The state or national team updates the portal's automated validation rules periodically during the data entry period. Data that the portal accepted in 2025-26 may fail in 2026-27 because the system has changed the thresholds.

Common validation changes catching schools off guard:

• Classroom-to-student ratio: If the number of classrooms you entered is much lower than the enrollment you entered, the 2026-27 validation now flags this as an inconsistency — whereas the 2025-26 validation did not
• Teacher-to-student ratio: The portal now flags extreme ratios (1 teacher for 200 students) for manual review, rather than automatically accepting them
• Age-class validation for students: Students significantly above or below the expected age for their class now generate validation warnings that you must acknowledge before saving

When you see a new validation error on a section you already filled: read the error message, fix the specific field it mentions, and save again. You must resolve all validation errors before the portal activates the Freeze/Submit button.

Pre-Entry Checklist for 2026-27 — Before Opening Any Module

1. Collect all student Aadhaar cards — identify which students lack Aadhaar and start CSC enrollment for them immediately
2. Do a physical school walkthrough — count functional toilets, working computers, CCTV, fire extinguishers, smart classrooms — separately "existing" from "functional"
3. Check teacher Aadhaar cards against Teacher Module entries — especially name format and date of birth
4. Verify 2025-26 data status — confirm with BRC that they fully certified last year's data, not just submitted it
5. Pull the APAAR status list from SDMS — find students from last year with missing APAAR IDs before you start new-year entry
6. Update teacher exit records — mark teachers who resigned, transferred, or retired since September 2025 inactive before you perform any new-year entry
7. List new students who joined and confirm they possess an Aadhaar card; for those without it, begin CSC enrollment now
