Developing skills for the Extended Project Qualification
Activity 3: Planning your project
Teacher notes
Learning Outcome: you will be able to produce a detailed EPQ project plan in a suitable format
Student activity
Teacher Notes
Find the assessment criteria for planning in the EPQ specification
that you are using. Producing evidence for planning involves the
skill of breaking down a project into its separate tasks and roles. In
this activity, you will critique an outline plan and develop ideas on
how to present a project plan.
This activity is particularly
suitable for small group work. If
carried out by an individual
student, they could discuss their
ideas at a mentoring session.
Sadie decided to carry out a practical investigation using an idea
from the IntoBiology website on medicinal plants at
http://intobiology.org.uk/student-project-medicinal-plants-andthe-inhibitory-effects-of-conifers/. She decided to present her
findings as a scientific poster.
Knowing when her final report had to be submitted to her teacher,
she planned the main stages between the start of her EPQ course
and the following March. Her planning is below:

below could apply to this plan,
the positioning of the research
after the project title has been
produced, and after the practical
work has been carried out, is a
problem worth emphasising.
4) February and March: make poster to show findings of the
experiment.
Breaking the tasks down into
sub-tasks, as suggested in this
activity, should involve allocating

microorganisms.
To discuss:
1) Suggest any ways that Sadie’s plan could be improved to
meet the EPQ assessment criteria for planning.
2) Once your group has agreed on the top four
improvements needed, ask your teacher for the list of

your discussions.

To do:

pair of students in your group.

have been allocated, decompose the main task into an
appropriate number of sub-tasks (individual steps). This

about the planning of this stage in detail.
5) Back in your group, swap the detailed stage plans. Each
student or pair of students should now comment on the
detail and quality of another student’s detailed stage plan.
Using a coloured pen, write onto the plan any further
changes that you think would help it to meet the EPQ
assessment criteria. Return the comments to the original
student/s.
To discuss:

6) In your group, discuss the best format for presenting and
tracking your plans. The format should allow you to show
when tasks are completed. You may need to add notes on
any updates and changes to your plan as you progress

can help with this.
Reflecting on learning:
7) List the key features of a good EPQ project plan.
8) List the aspects of good planning that you think you are
confident about, and those which will you need to pay
more attention to.

Planning tips for EPQ projects
1 Some tasks need to take place in advance of the main project activities. For example, you’ll
need to organise sufficient consumables and equipment for the practical well ahead of the
planned practical work. This may involve submitting an order to technicians.
2 It is useful to add other important deadlines in your life into your EPQ plan, so you can
prioritise your time during busy periods.
3 There will be important dates and deadlines to add to your plan, such as meetings with your
mentor and completion of paperwork for the awarding body.
4 Research and reading around the topic for your project should start ahead of deciding the final
project title and should carry on informing your project as you proceed.
5 Plans should include an estimate of the amount of time needed for individual tasks.
6 You need to show that you are going beyond carrying out practical protocols that are available
on a website, for example by adapting them to answer your specific question.
7 Tasks sometimes depend on completion of other tasks (dependencies). Deadlines for these key
tasks need to be shown on a plan.
8 Tasks need to be broken down into detailed sub-tasks so that the timeline, dependencies
(tasks which reply on other tasks being completed) amount of time needed for a task and any
people involved are shown.
9 An EPQ plan needs to be set out in a way that allows any changes and updates to be shown.
These will be monitored by your mentor against the original plan.
10 Any project artefact or outcome needs careful planning to identify time, materials, people
and meetings etc. that are needed.
11 A plan should include details of the areas that you need to research and possible sources of
information.
12 If a project involves consulting experts, time for this should be built into the planning.
