The IB places great value on external validation of its programmes, curriculums and professional development. A recent Global International Schools’ Assessment study found that PYP students outperformed non-IB students in mathematics, reading and writing. Additional studies on programme impact, quality assurance, programme development and assessment research are available at www.ibo.org/research.
Have studies been done on the impact of PYP?
