Explanation
The consultant should install the K-12 Architecture Kit from GitHub to evaluate it for the school district.
GitHub is a platform that hosts code repositories and allows users to collaborate on software development projects. The K-12 Architecture Kit is a solution that extends EDA to meet the needs of K-12 schools. The K-12 Architecture Kit provides objects and features to track student information, such as grades, attendance, and program enrollments. The K-12 Architecture Kit is not available on the AppExchange, but rather on GitHub as an open source project that users can install and customize. Installing the K-12 Architecture Kit from the AppExchange, starting a new K-12 Architecture Kit trial, or making K-12 Architecture Kit record types available to profiles are not actions that the consultant can take to evaluate it for the school district.
