Internal assessment

The Hachette textbook contains a 40 page guide to the Internal Assessment. For each of the 5 criteria, it includes:

  • The official IB assessment criteria text
  • Top tips and common mistakes
  • Exemplar samples (separate to the IB authored samples)
  • Detailed checklist

Those who found my guide to the IA for the previous syllabus useful, should find the chapter in the Hachette textbook very helpful for navigating the new IA.
