The generator-like logo was created to mark Yio Chu Kang Secondary’s relocation to bigger premises in 1982. Then principal Mdm So Bie Leng worked with two art teachers to revamp the school's shield-like crest to this more modern design that better reflected its motto “Pursuit, Knowledge, Service”.

At its core is the letter ‘Y’ to stand for the school’s name, with three blades representing the values in the original motto. The ‘Y’ and three blades are bound by a circle that represent the staff and students.
