Hi,
Have you been officially nominated and accepted into the program? This is an essential step; the course is only offered to program candidates, so it is not visible in the Partner Academy by default.

If you are not aligned with a Partner Solutions Architect at Databricks, and do not have a Partner CoE or another Partner Champion in your organization to connect you with the right person at Databricks, please reach out to partners@databricks.com with details including your current employer, any details you have regarding the prerequisites for the program which can be found in the program guide on the Partner Portal here. https://partners.databricks.com/s/databricks-partner-champions-program.

Let me know if you need further assistance.
