How to consult education rate for a specific animal?
You can access the overall education rating, the education rating per species and other education related information by going to the "Zoo" tab in the bottom left corner, then selecting "Education" in the left bar. Hover over various items to see what they mean.
When you have such a goal, the current education rating is also shown near the goal itself in the Challenges screen.
To reach the goals, research the animal fully (using Vet Research), place education boards and education speakers, and place down information kiosks where people can buy audio guides.
