The paper found the IB diploma’s subjects were similar to those in the HSC, but « are generally thought to be more advanced in their depth and breadth ». Offering it would « help attract and retain families of bright students in the public school system », says the proposal to education executives from the department’s Centre for Education Statistics and Evaluation. Content « tends to be at a university undergraduate level, with greater use of open-ended questions and skills of problem-solving ». Former Board of Studies chief executive Carol Taylor said introducing the IB to public schools had long been considered, but the hurdles had been cost and uncertainty over how many students would choose it. The HSC is more flexible as it caters for students who had different strengths. []
