Which feature within check-in allows users to track their skill improvement over time?

The feature that allows users to track their skill improvement over time is the skill enhancement tracker. This tool is specifically designed to help individuals monitor their progress and development in specific skills over time. It provides a structured way for users to see how their capabilities have grown, allowing for a better understanding of their learning journeys and areas that may need additional focus.

While other options, such as feedback surveys and rate my interest, play important roles in the check-in process—facilitating feedback from peers or assessing one's enthusiasm towards certain skills—they do not directly track improvement over time in the way a skill enhancement tracker does. Skill validation also serves a purpose, but it is more about confirming the current level of a skill rather than monitoring progress over a duration. The skill enhancement tracker, on the other hand, is directly aligned with tracking and demonstrating skill growth.
