The Member of Parliament for the constituency is People's Action Party (PAP) Amy Khor.

The constituency was carved out of Hong Kah Group Representation Constituency (GRC) as a SMC during the 2011 elections as Hong Kah is no longer in existence except for the upcoming MRT station.

In 2020, parts of Jurong West (Bulim) were transferred to West Coast GRC, and parts of the Tengah ward from Chua Chu Kang GRC were transferred to this constituency.

This is due to the growing development of Tengah New Town and also the remaining public housing projects in Bukit Batok West.

In the next elections, the Tengah ward will be returned back to Chua Chu Kang GRC.
