Kersten was succeeded by Zandt, under whose leadership the SGP was very stable, continually getting 2% of votes. In the [[1956 Dutch general election|1956 general election]], the SGP profited from the enlargement of parliament, and entered the [[Senate (Netherlands)|Senate]] for the first time. It lost that seat in [[1960 Dutch Senate election|1960 Senate election]], but regained it in the [[1971 Dutch Senate election|1971 Senate election]].<ref name="Parlement.com">{{Cite web|url=https://www.parlement.com/id/vh8lnhrouwy4/staatkundig_gereformeerde_partij_sgp|title=Staatkundig-Gereformeerde Partij (SGP)|work=[[Parlement.com]]|access-date=18 August 2024|language=nl}}</ref>

In 1961 Zandt died and was succeeded by Van Dis sr. After ten years he stood down in favour of Reverend [[Hette Abma]], who also stepped down after ten years, in favour of [[Henk van Rossum]], a civil engineer. In the [[1984 European Parliament election in the Netherlands|1984 European Parliament election]], the SGP joined the two other orthodox Protestant parties, the [[Reformatory Political Federation]] (RPF) and the [[Reformed Political League]] (GPV). They won one seat in the European Parliament, which was taken by SGP member [[Leen van der Waal]], a mechanical engineer.<ref name="Parlement.com"/>

In 1986, Van Rossum was succeeded by [[Bas van der Vlies]]. In the [[1994 Dutch general election|1994 election]] the party lost one seat in the House, [[1998 Dutch general election|regained it in 1998]], and [[2002 Dutch general election|lost it again in 2002]]. During the [[2003 Dutch cabinet formation|2003 cabinet formation]], the [[Christian Democratic Appeal]] (CDA) and the [[People's Party for Freedom and Democracy]] (VVD) held talks with the SGP — the first time that the SGP was seriously considered as a possible coalition partner. Ultimately, the [[Democrats 66]] joined the [[second Balkenende cabinet]] instead of the SGP, mostly because of the ideological differences between the VVD and the SGP.<ref name="Parlement.com"/>

In 2010, [[Kees van der Staaij]] succeeded Van der Vlies. During the [[2010 Dutch cabinet formation|2010 cabinet formation]], the negotiating CDA, VVD and [[Party for Freedom]] (PVV) took into account some wishes of the SGP, so that SGP would provide [[confidence and supply]] in the Senate where the [[first Rutte cabinet]] did not have a majority.<ref name="Parlement.com"/>
