Mapper pro and educational features are the same if you are comparing identical software versions. You will have all of the latest features if you have the latest version of the software.
If your Mapper-edu-class license has expired Support and Upgrade, which appears to be the case, this means that you cannot access the latest version of the software with this license. You are currently using an outdated version of the software with this license that doesn’t have automatic point cloud classification, as this was introduced in version 4.0.18 (see this page).
You can extend your Support and Upgrade to get access to the latest features. Visit the page here and click _E_xtend now under the appropriate license to extend your upgrades to get access to point cloud classification.
