LEED offers several certification programs, some of which are currently being piloted or developed.

With the exception of LEED-Neighborhood Development, each of the LEED certification programs offers points to be gained in six broad categories:

1. Sustainable site planning
2. Safeguarding water and water efficiency
3. Energy efficiency and renewable energy
4. Conservation of materials and resources
5. Indoor environmental quality
6. Innovation and design process

The single-family home category (LEED for Homes) — which launched in January 2008 — also includes points for location and linkages, such as building within one-half mile of public transportation and other community services, as well as homeowner education and awareness.

Based on the number of points earned, LEED provides four progressive levels of certification: Certified, Silver, Gold and Platinum.
