Hello, I'm a graduate student working on multimodal brain tumor segmentation. The registration page shows "Challenge is closed." Is there any way to obtain validation-set scores for BraTS 2023 after the challenge, or is the evaluation queue permanently closed? If it is closed, would you recommend BraTS 2024/2025 for benchmarking instead? Thank you.

Hi @HyunbinChoo , You can register for continuous benchmarking on the challenge-specific page here: https://www.synapse.org/Synapse:syn51156910/wiki/622351 Hope this helps!
Hi @astaraki, Thank you for your earlier reply. I'd like to follow up with a more specific question, as I may have been unclear before. I was asking specifically about the **Continuous Evaluation: Adult Glioma** track (syn51156910/wiki/622971). The wiki page for "1. Segmentation – Adult Glioma" states: > "While the BraTS 2021 and 2022 challenges are now closed, continuous evaluation for the BraTS 2023 validation set is still accepted until further notice." The leaderboard on that page also shows submissions as recent as July 2026, which suggests the queue is still active. Could you confirm: 1. Is the Adult Glioma continuous evaluation queue still accepting new submissions? 2. Is there any known end date, or does "until further notice" mean it remains open indefinitely for now? I'm planning to use this as the benchmark for a journal paper, so I want to be certain before committing to the 2023 dataset rather than moving to BraTS 2025. Thank you for your time. Best regards, Hyunbin Choo
Hi @HyunbinChoo Thanks for reaching out. It might be possible that the continuous evaluation queues for some tasks become available next year. But for now, there isn't any plan to reopen the evaluation pipeline for the previous years' challenge. If reopening becomes the case, we will announce it via the Synapse platform.
