Practical Work

Internal assessment is an integral part of the environmental systems and societies course, contributing
20% to the final assessment. This weighting should be reflected in the time that is allocated to teaching the
knowledge, skills and understanding required to undertake work as well as the total time allocated to carry
out the work.

It is recommended that a total of approximately 30 hours should be allocated to practical work (excluding
time spent writing up work). This should include:
  • time for the teacher to explain to students the requirements of the internal assessment
  • the course ethical guidelines
  • class time for students to work on the internal assessment component
  • time for consultation between the teacher and each student
  • time to review and monitor progress, and to check authenticity.
