and highest amateur tier called Topklasse, and Hoofdklasse clubs have been able to get promoted to that new division. Before the 2008–09 season, Hoofdklasse clubs could be promoted by obtaining a professional license. However, only a club going bankrupt or losing its license could result in clubs leaving professional football. The last clubs leaving professional football in that way were FC Wageningen and VCV Zeeland in 1992, and more recently HFC Haarlem and RBC Roosendaal, who went bankrupt in January 2010 and June 2011 respectively. The most recent additions to the league were AGOVV Apeldoorn in 2003 and FC Omniworld in 2005, expanding the league to 19 and later 20 clubs. However, for the 2010–11 season, the league returned to 18 clubs, as HFC Haarlem went bankrupt and FC Oss were relegated to the newly formed Topklasse. The 2012–13 season ended with 16 teams after AGOVV and SC Veendam went bankrupt. Four teams have been added to bring the division back up to 20 teams in 2013. Achilles '29 has been promoted from the Topklasse with the reserve teams of Ajax, FC Twente and PSV being added as well. Since the 2016–17 season there is optional relegation to the third-tier, amateur Tweede Divisie. Clubs in the Tweede Divisie had to announce in mid-season if they want to be eligible for promotion. Only if one of those clubs won the Tweede Divisie championship is a team relegated from the Eerste Divisie. The remainder of the 2019–20 season was cancelled amid the coronavirus disease 2019 (COVID-19) pandemic, thus there were no promotions or relegations. Before the cancellation, the KNVB met in December 2019 and ruled that promotion to the second division and relegation to the third were suspended until 2022–23, and that the lowest-ranked Eerste Divisie Jong team will exchange places with its highest-ranked Tweede Divisie counterpart.
