Why Class 1 Entry Is Different From Other Classes

Every other class in UDISE+ involves promoting students from last year. Class 1 is the exception. Every single child is a completely new record — no previous profile, no existing APAAR ID, no data to pull forward. For a school that admitted 60 new Class 1 students, that means the operator must fill 60 fresh entries, verify 60 Aadhaar cards, and generate 60 APAAR IDs.

And unlike promotions, Class 1 entry fails in very specific ways: the Aadhaar name does not match the school register name, the date of birth on Aadhaar shows only a year without the exact date, or the student already has an entry from an Anganwadi or pre-primary school. Each failure stops the entry process until you resolve it.

This page covers the 5 specific problems that block Class 1 student data entry — and the exact steps to fix each one.

Problem 1: APAAR ID Not Generating After Aadhaar Entry

You entered the student's Aadhaar number and clicked Authenticate, but the system did not generate the APAAR ID, or the authentication failed.

Check these in order — the problem is almost always one of the first two:

1. Name mismatch. Open the physical Aadhaar card. Type the child's name exactly as printed on it — character by character — into the SDMS form. Common mismatches: "Shraddha" vs "Shradha," "Mohd." vs "Mohammed," all-caps on Aadhaar vs mixed-case in your form. The UIDAI database matches the exact string, not a phonetic version.
2. Date of birth not matching. Verify the exact DOB — day, month, year — from the Aadhaar card. School admission registers sometimes record DOB differently from Aadhaar (especially for families who registered a few days off for convenience). The SDMS form must match Aadhaar, not your register.
3. Aadhaar not yet active. If the family enrolled the child's Aadhaar recently (within the last 30-90 days), UIDAI may not have activated it in their authentication database yet. Check the status at uidai.gov.in. If it is not active, wait for UIDAI to activate it, then authenticate.
4. Aadhaar linked mobile not available for OTP. If authentication requires an OTP sent to the mobile registered in the child's Aadhaar—and that number belongs to a parent who is not present—you cannot enter the OTP. Call the parent for the OTP or reschedule the entry for when they are available.

Problem 2: Student Name in School Register Does Not Match Aadhaar

This is the most common Class 1 data entry bottleneck. Parents often gave a nickname or informal name when enrolling the child, and the official Aadhaar has the formal name.

Example: The school register says "Riya Sharma." The Aadhaar says "Priya Kumari Sharma." These are different enough that Aadhaar authentication will fail for "Riya Sharma."

What you should do:

• Use the Aadhaar name for SDMS entry. Change the name in SDMS to match Aadhaar, not the other way around.
• Update the school admission register to also reflect the Aadhaar name — or note the Aadhaar name alongside the registered name.
• Do not alter the Aadhaar. Aadhaar corrections take time, and you cannot delay the data entry deadline. Use whatever name the Aadhaar shows today for SDMS entry.
• If the Aadhaar itself has an obvious spelling error (e.g., "Rahool" when the family says the correct spelling is "Rahul"), advise the family to correct the Aadhaar at the nearest centre—but use "Rahool" in SDMS for now until the registry processes the correction.

Problem 3: Aadhaar Shows Only Birth Year — No Exact Date

For children who enrolled in Aadhaar before age 5, UIDAI sometimes records only the year of birth (e.g., "2020") without the exact date. The SDMS form requires the DD/MM/YYYY format.

This creates a real problem—you cannot authenticate the student by DOB if you only know the year.

What most schools do—and what works in most states:

• Enter the DOB as 01/01/YYYY (January 1 of the birth year)—this represents the standard convention for year-only Aadhaar DOBs
• Some state portals accept this; others may still flag it — contact your Block MIS Coordinator to confirm the accepted format in your state
• Do not make up a date — if the family knows the actual birth date from the birth certificate, use that and note the discrepancy with Aadhaar

Problem 4: Same Student Appearing Twice in SDMS

The portal says "Student already exists" when you try to add a Class 1 student. Or a student appears in the list with a partially filled profile you did not create.

This happens when:

• A teacher previously enrolled the child at an Anganwadi or pre-primary school that also uses SDMS
• A data entry operator started the entry earlier and saved a draft
• Another school in the same block has entered a student with the same Aadhaar (a data error that requires district-level resolution)

What you should do:

1. Search for the student using their Aadhaar number — not their name
2. If an existing record appears with the correct Aadhaar, open it and check which school the system links it to
3. If the system links it to a pre-primary school or Anganwadi, click "Transfer to My School" or "Link to My School"
4. If the system links it to a completely different school that you do not recognize, report this to your Block MIS Coordinator—another school may have made a data entry error using the wrong Aadhaar

Problem 5: What to Do When a Student Has No Aadhaar at All

Some Class 1 students—especially those from migrant families or remote areas—may not have Aadhaar yet. You cannot generate an APAAR ID without Aadhaar. Here is what you should do:

1. Enter the student's complete GP and EP data in SDMS and save—leave Aadhaar and APAAR fields blank
2. Give the family a written note explaining that the government requires Aadhaar enrollment for the academic identity card (APAAR). Mention the nearest Common Service Centre (CSC) or Aadhaar enrolment camp in the block
3. Maintain a separate register at school of all students pending Aadhaar enrollment, listing their names and class
4. Submit this list to your Block MIS Coordinator before the data submission deadline—this documents the pending cases and protects your school from certification rejection
5. As soon as you receive the Aadhaar, open SDMS, find the student, add their Aadhaar number, authenticate, and generate the APAAR ID

Correct Order for Adding Class 1 Student — Step by Step

1. Collect all Class 1 students' Aadhaar cards before opening SDMS
2. Compare each Aadhaar name against your admission register — note all differences on paper
3. Login to SDMS at sdms.udiseplus.gov.in
4. Click "Add New Student" and enter the student's Aadhaar number first—check if the system already contains a record
5. If new: fill General Profile (GP) — use Aadhaar name, Aadhaar DOB, parents' names, address
6. Tick the Parent Consent checkbox
7. Click "Authenticate Aadhaar"—wait for the system to send an OTP to the parent's Aadhaar-linked mobile
8. After successful authentication, click "Generate APAAR ID"—wait for the "Saved" confirmation
9. Fill Enrollment Profile (EP) — Class 1, section, roll number, admission number
10. Fill Student Facilities (SF) — mid-day meal, free textbooks, uniform, RTE admission
11. Click Save — proceed to next student
