JoSAA 2026 B.Arch Choice Filling – Process & Strategy Guide

Choice filling for B.Arch and B.Planning seats in JoSAA follows the same broad mechanics as the main B.Tech choice-filling process — candidates log into the JoSAA portal, browse eligible institute-program combinations, add them to a preference-ordered list, and lock or leave the list open until the deadline. However, because the B.Arch/B.Planning seat pool is dramatically smaller than the B.Tech seat pool, the strategic considerations for building this list differ in important ways.

Similarities to Main B.Tech Choice Filling

• Same JoSAA portal and login credentials are used for both tracks.
• Same underlying seat allotment logic — a centralized algorithm processes preferences against ranks to produce the "best possible" allotment for each candidate.
• Multiple rounds of allotment, with freeze/float/slide/withdraw options at each round, mirror the B.Tech process structurally.
• Category-wise (General/OBC-NCL/SC/ST/EWS/PwD) and Home State/Other State quota reservations apply similarly.

Key Differences from B.Tech Choice Filling

Step-by-Step Choice Filling Process

1. Complete JoSAA registration and verify your Paper 2A/2B rank and eligibility.
2. Browse the list of participating institutes offering B.Arch or B.Planning for the year.
3. Add each institute-program combination you'd be willing to accept to your choice list.
4. Arrange choices strictly in order of genuine preference — most preferred first.
5. Review and lock your choices before the deadline; unlocked lists auto-lock at the cutoff time using the last saved order.
6. Respond to each round's allotment result — freeze (accept and stop), float (accept but remain open to upgrades), or slide (accept within the same institute for a different eligible program), or withdraw if you no longer wish to continue.

Strategic Tips Given the Smaller Seat Pool

Because there are simply fewer B.Arch and B.Planning seats overall, students should avoid being overly selective in their choice list — list every combination you'd genuinely accept, even ones that seem like backups, since a narrow list increases the risk of not receiving any seat at all. Simultaneously, don't rank low-preference options above genuinely preferred ones just because they seem "safer" — the allotment algorithm always tries to give you your highest-ranked eligible choice, so there's no strategic advantage to ranking a less-preferred option higher.

Common Mistakes to Avoid

A frequent error among B.Arch aspirants is filling too few choices, mistakenly believing that since seats are limited, adding more options won't help. In reality, a longer list only improves your chances since it gives the algorithm more valid options to consider on your behalf — it never hurts you to add an eligible choice you'd genuinely accept. Another common mistake is neglecting to research each institute's specific program details before ranking, leading to choices based on name recognition alone rather than actual fit. Students should also avoid leaving choice-filling to the last day, since technical issues or last-minute confusion can result in an incomplete or poorly-ordered list at the lock deadline.

Understanding Freeze, Float, and Slide Options

After each round of allotment, candidates must respond to their allotted seat using one of three options. Freeze means accepting the seat and exiting the counselling process entirely for future rounds — a good choice if you're fully satisfied with your allotment. Float means accepting the current seat provisionally while remaining eligible for a potential upgrade to a higher-preference choice in later rounds, useful if you'd accept your current seat but still hope for something better. Slide means staying within the same institute but becoming eligible for a different eligible program at that institute, relevant if you're open to other options within your preferred campus. Choosing correctly at each round is just as important as the original choice list order.
