* As part of a larger development: Large-scale residential developments (e.g., master-planned communities) frequently incorporate schools as an amenity to attract residents. The developer might build the school itself, or work with a school district to ensure one is built concurrently.
* As a separate, but related project: A developer might focus on building the infrastructure (roads, utilities) for a new school site, which is then developed by a school district or other educational entity.
* Public-private partnerships: Developers can partner with public entities to build and/or finance schools, often sharing the costs and responsibilities.
So, the answer is yes, but the involvement of the real estate developer can vary significantly depending on the project and the relationships with government and educational institutions.
