Lab Reports & Rubrics

Internal Assessment in IB Biology

Important note: these documents are used in my own classes, though are not official IB products. They are shared in good faith, but treat them with caution and due diligence. Teachers must always refer to the most up-to-date advice from the subject guides, subject reports on the OCC and experts in the subject. 

Tip: to print your completed rubric, first save as a pdf file- it doesn’t confuse the printers.

This version is submitted by my students:

There is a published set of IA guidance and sample assessed student work on the IB Biology Teachers Support Material page. Occasional updates to the Triple A Learning IB Biology blog also address IA and assessment.



LabWrite is an online tool to help structure good-quality write-ups. Work through the steps of a lab report using this resource and check your report against the checklist and rubrics above. Does it help you work towards those ‘complete’ marks?


Make sure you pay attention to the IB’s:

For teachers

Download the Turnitin GradeMark QuickMark comment databases that I use here. They correspond to the self-assessment codes in the rubric above, and will only work if your school subscribes to the full Turnitin WriteCycle suite.

Some others:
If your school is already using Turnitin, it is well worth asking for access to the full suite of tools. They have a discount for IB schools and you can give quality, paperless feedback.
The presentation below outlines how these can be used (you don’t need to have Moodle):
  1. Hi Stephen,

    I have just started teaching IB Biology and I was really impressed by your website! Hats off to you for opening up so many resources to newbies like me!! I found your IA rubrics and feedback form very precise and useful. With your permission, can I use it to give feedback to my students about their IA work?

    Thanks and regards,

  2. Hi Stephen,

    Similarly I find your rubric very helpful.

    I’ve adapted it slightly to a version that would suit my students. Before I go ahead and use it can I email it to you to make sure you are happy both with what I’ve done and that I have of course credited you?

    • Hi Chris,

      Sure – though you can use it as you see fit with your students. I hope it is helpful. Thanks for the donation!
