What milestone was achieved regarding human spaceflight occupancy at the ISS before Goldin's departure?

Answer

The beginning of permanent human occupancy in space

A monumental achievement marking the success of Goldin's transformation of the International Space Station (ISS) program occurred just before his term ended. Specifically, the beginning of permanent human occupancy in space was realized when Expedition 1 arrived at the station in November 2000. This was the culmination of transforming the original Space Station Freedom concept, integrating a massive Russian partnership, and leveraging the preparatory work done during the preceding Shuttle-Mir Program. Goldin's expressed vision was to ensure humanity would maintain a continuous presence in space indefinitely, making the establishment of continuous occupancy a defining success of his tenure.
