Case Studies and Portfolio Entries

You Need to Complete Case Studies or a Portfolio in Your Programme at The National School of Aesthetics

Case studies indicate your understanding and critical thinking regarding treatments you are delivering, and documents this for us to assess if you are studying the New Zealand Certificate and Diploma in Beauty Therapy. Portfolio entries not only show the same information case studies do but also documents additional hours you complete outside of your programme at The National School of Aesthetics if you are studying the New Zealand Certificate in Nail Technology.

General Information about Case Studies and Portfolio Entries

Case Studies

A case study is written documentation of work you have carried out on a client. A case study should reflect your competence in and knowledge of the subject. Case studies are a requirement of the New Zealand Certificate and Diploma in Beauty Therapy programme.

We will give you case studies to complete throughout your time training with us. You will need to complete all of them fully and successfully to pass your programme.

These assignments are compulsory.

Case studies are:

  • required assessments that count towards your overall grade

You must achieve:

  • 60% overall in case studies with a minimum pass of 60% in each case study

All case studies must be handed in to a passable standard in order to qualify.

All work must be your own work. You will need to think critically about the treatment you are giving and report back on all steps of your work with your model. Some case studies and all portfolio entries require photographic evidence of your work.

Case studies of a poor standard will be returned to you, and you will need to redo those case studies and hand them in again. You only have one opportunity to do this. See the Rules and Regulations for more information.

ITEC now calls case studies evidence of treatments. These are still, in essence, the same thing.

  • These are completed under the guidance of your tutors, who will monitor the quality of your written work.
  • Each case study should take 3-5 hours work: practical and written. Some can be started in class and then completed at home, but for the majority should be completed outside of class.
  • Certain treatment assignments are due at various times of the year. See the Case Studies Due Dates for your due dates during the course.
