# Out-of-Sample Evaluation Phase
## Out-of-Sample Evaluation Phase
During the Out-of-sample (OOS) phase, your submissions will undergo iterative scoring, released each Monday at 6 PM CEST, from Monday, August 28th, and concluding on Monday, November 20th.
### **Leaderboard Update**
The leaderboard will be regularly updated on a weekly basis. The mean score will be calculated as the average Spearman correlation across all Out-of-sample `dates` released from the inception of the Out-of-Sample phase. This approach will progressively mitigate score volatility, leading the leaderboard to increasingly reflect the structure of the final rankings over time.
### **In-Depth Scoring Breakdown**
Detailed performance metrics for your Out-of-sample submissions are available within the Out-of-Sample Performance section on [your submission](https://adialab.crunchdao.com/projects/@me) page. You will have access to the following information:
* The performance of the selected submission, on a **per-date** basis.
* A comprehensive breakdown of your performance on your Out-of-Sample run, presented on a **per-date** basis.
