NATA Answer Key 2027: Expected April 2027, Download PDF and Objection Window

The Council of Architecture (COA) will release the NATA 2027 Answer Key on the official website nata.in separately after each phase of the examination. As of August 2026, NATA 2027 is yet to be scheduled and conducted. Based on previous cycles, the answer keys for all three phases of NATA 2027 are expected to be released between April and September 2027.

• COA will release separate provisional answer keys for NATA 2027 Phase 1, Phase 2, and Phase 3 on nata.in — typically within 7–10 days of the respective phase exam date.
• Only the objective sections (Part A: Mathematics & Physics-Chemistry and Part B: General Aptitude) will have a published answer key; the drawing component (Part C) is evaluated by a COA expert panel and does not have a public answer key.
• Students can submit objections against the NATA 2027 Provisional Answer Key through the official portal during the challenge window, which is usually open for 2–3 days after each provisional key is published.
• The NATA 2027 Final Answer Key will incorporate all valid challenges and will serve as the basis for official score computation and result declaration.

You can use the final NATA Answer Key 2027 alongside your response sheet to estimate your objective-section score and gauge your overall performance before the official result is declared.

In 2026, over 60,000 students registered for NATA across all three phases — making it one of the most widely taken architecture entrance tests in India and the primary gateway to B.Arch admissions at over 1,000 institutions.

NATA 2027 Provisional Answer Key  (Soon)

The provisional NATA 2027 Answer Key will list the officially correct responses to every objective question (Part A and Part B) administered in each phase. COA publishes phase-wise answer keys shortly after each test window, giving students an early opportunity to verify their answers and file objections before the final key is issued. Part C (drawing) is graded by expert architects and will not appear in the published answer key.

NATA 2027 Unofficial Answer Key

Several architecture coaching institutes and online preparation platforms typically publish unofficial answer keys for NATA shortly after each phase. While these are not authoritative, they can give students a preliminary estimate of their objective-section performance before COA releases the official answer key.

Details Mentioned on NATA Answer Key 2027

The official NATA 2027 Answer Key will carry all the information you need to verify your responses against the correct answers for the objective sections. Here is what the document typically includes:

• Examination name (NATA 2027) and phase number (Phase 1 / Phase 2 / Phase 3)
• Date and shift of the exam
• Question numbers with the officially correct answers for Part A (Mathematics, Physics & Chemistry) and Part B (General Aptitude)
• Subject-wise and section-wise segregation of questions and answers
• Instructions on how to compare the answer key with your response sheet to estimate your objective-section score
• The challenge/objection window period and the process to raise a query against a specific question

Note: The NATA 2027 Answer Key covers only the objective sections (Part A and Part B). The drawing section (Part C) is graded by a panel of expert architects appointed by COA and does not appear in the published answer key document.

How to Challenge the NATA Answer Key 2027?

If you believe that any answer published in the NATA 2027 Provisional Answer Key is incorrect, you can submit a formal objection through the official COA portal during the notified challenge window. All objections are reviewed by an expert panel. If a challenge is found valid, COA revises the answer in the final key — and the revised answer is then used to recompute scores for all students.

Here are the complete guided steps to challenge the NATA 2027 Answer Key:

• Log in to your candidate account at nata.in during the challenge window period announced by COA.
• Navigate to the "Raise Objection" or "Answer Key Challenge" link from your dashboard.
• Select the phase and the specific question number you wish to challenge.
• Choose the appropriate objection category (e.g., incorrect answer, ambiguous question, printing/display error) and provide a detailed justification supported by references from standard textbooks or approved study material.
• Pay the applicable challenge fee as specified in COA’s official NATA 2027 notification. The exact fee amount will be confirmed by COA at the time of provisional key release.
• Submit your objection before the challenge window closes — late submissions will not be entertained under any circumstances.
• COA’s expert panel will evaluate all objections. Where challenges are accepted, the answer key will be corrected in the final version published thereafter.

Note: Objections can only be raised against Part A (PCM) and Part B (General Aptitude) questions. The drawing section (Part C) is not subject to the challenge process, and its marking by COA’s expert panel is final.

How to Calculate Your Score Using the NATA Answer Key 2027

After the NATA 2027 Answer Key is published, you can compute your expected score for the objective sections by matching it with your response sheet. Since your drawing score (Part C) is awarded by COA’s expert panel and not available until the official result, only the objective portion can be self-calculated.

• Download both the NATA 2027 Provisional Answer Key and your Candidate Response Sheet from nata.in.
• For every question in Part A (Mathematics, Physics & Chemistry) and Part B (General Aptitude), check whether your recorded response matches the answer key.
• Add +1.5 marks for each correct answer in the objective sections.
• There is no negative marking in NATA — questions you answered incorrectly or left unanswered carry zero marks.
• Sum all earned marks from correct objective responses to get your estimated Part A + Part B score.
• Your full estimated total = Objective Score + Drawing Score (the drawing component will be disclosed by COA in the official result).

Note: Only the official NATA 2027 Result declared by COA will contain the final verified score. All self-computed estimates using the answer key are approximations for planning purposes only.

NATA 2027 Marking Scheme (Based on NATA 2026 Pattern)

Note: The marking scheme above reflects the NATA 2026 pattern. COA may update the structure for NATA 2027. Always verify against the official NATA 2027 Information Brochure published at nata.in before the examination.

NATA Marks vs Rank 2027

The table below provides an approximate correlation between NATA scores (out of 200) and expected All-India merit positions, based on historical score distributions from NATA 2025 and 2026. Unlike JEE, NATA scores are used directly by institutions for admissions, so the "rank" reflects approximate merit standing on COA’s All-India merit list. Actual 2027 figures will depend on total registrations, difficulty level, and COA’s normalization procedure, if any.

Note: This marks vs rank table is based on historical NATA trends and serves as a reference estimate only. Official NATA 2027 merit positions will be published by COA on nata.in after result declaration.

Colleges Accepting NATA 2027

NATA 2027 scores are recognized by over 1,000 B.Arch programmes across India — spanning central institutions, IITs, NITs, state government colleges, and private universities. Each college sets its own minimum NATA score cutoff and may combine the NATA score with Class 12 marks for merit calculation. Always verify admission criteria directly with the institution before applying.

Note: NATA score weightage, eligibility conditions, and counselling procedures vary by institution and state. Always check the individual college’s official admission notification for NATA 2027-specific requirements.
