# Competency models in the HyperSkill Platform
Reading skill mastery and competency model results in HyperSkill Platform.
In the HyperSkill Platform you can view the performance data of all the learners who played a simulation. You can view either:
* The aggregate performance across all learner sessions, which shows the average skill mastery of the overall model and of each specific skill assessed.
* The skill mastery breakdown of an individual learner session.
Every skill starts a run at 0.5, or 50%.

Note: You will not be able to see performance rating information if a competency model has not been attached to the simulation through HyperSkill Studio. See Competency models in HyperSkill to learn how to attach a competency model to a simulation.

Example of the Overall Mastery and Skill Mastery of an individual learner session.
## View the competency model
To see more about the competency model used in a simulation, click **View Competency Model** in the **Skill Mastery** or **Average Skill Mastery** section. The model opens in a tree format, with more information about the average mastery of individual skills across all users of the simulation.
For how the numbers are calculated, see How scores work.
