Teams
Promotion and relegation
A total of 14 teams competed in the 1999–2000 season, 2 less than the previous where 16 teams competed. Of these 14 teams, 13 were from the 1998–99 season with Shqiponja being the only promoted side from the Kategoria e Dytë. 3 sides from the 1998–99 season were relegated, and they were Burreli, Laçi and Besa.
Tirana and Tomori finished the season level on points so the Albanian Football Association decided to organise a championship playoff game to determine the winner of the 1999–2000 Albanian National Championship. The game was played at Ruzhdi Bizhuta Stadium in Elbasan and Tirana won on penalties following a 1–1 draw to retain their title. Had the league been decided on goal difference Tirana would have won it, but if it had been decided on their head-to-head record Tomori would have won it.
Elbasani finished in penultimate place in the league, and although they were not automatically relegated like Partizani, they were placed in a relegation/promotion playoff against the Kategoria e Dytë playoff runners-up Besa. The game took place on 7 June 2000 in Tiranë and Besa won 2–1, thanks to goals from Armand Daiu and Demneri, to earn promotion to the 2000–01 National Championship, with Elbasani being relegated down to the Kategoria e Dytë.
