Google+ is available for all students in a G Suite for Education domain.

Google+ is no longer available for use within G Suite for Education domains. The platform was officially shut down in April 2019, which means that students in a G Suite for Education domain cannot access Google+. This reflects Google's broader strategy to focus on other collaborative tools and services that are better suited for educational purposes, such as Google Classroom and Google Meet. Therefore, the assertion that Google+ is available for all students in a G Suite for Education domain is incorrect.

In this context, the presence of other choices such as availability solely for teachers or selected students does not apply either, given that the platform itself has been discontinued and is not accessible to any user, whether students or teachers.
