The Illawarra Grammar School, abbreviated as TIGS or Illawarra Grammar, is an independent Anglican comprehensive co-educational early learning, primary and secondary day school, located at Mangerton in the Illawarra region of New South Wales, Australia. The school caters for approximately 1,100 students from early learning to Year 12. TIGS offers an early learning program for students between 3 and 5 years of age called TIGS Prep (previously titled, The Piper Centre).[1] The School employs 97 teaching staff and 48 non-teaching staff. A total enrolment of 778 students consists of 407 boys and 371 girls as of 2019.[2]
The Illawarra Grammar School was founded in 1958 by Bishop Gordon Begbie and dedicated parents. On its opening day, 3 February 1958, the first headmaster, Rev. Richard Bosanquet and two staff, welcomed 28 students into the school. In 1975, the school became co-educational when it amalgamated with SCEGGS 'Gleniffer Brae'.[3] In 2009 TIGS celebrated the Golden Jubilee of its founding.[4]
At the end of 2018, TIGS announced the appointment of the eighth Principal, Judith Nealy, as the successor for long-serving Headmaster, Stephen Kinsella.[5] In 2024, Dr Julie Greenhalgh commenced as the ninth Principal.[6]
