Sustaining experimentation and development: keeping the project developing across its whole length; purposeful experimentation that feeds the enquiry; avoiding stalling, repetition or premature resolution.

What this dot point is asking

Sustained development is what separates a top-band project from a skilful but static one, and it is hard to maintain across a long project. This dot point is about keeping the work developing across its whole length, experimenting purposefully so it feeds the enquiry, and avoiding the three traps of stalling, repetition and premature resolution. It is central to AO1 and AO2, both of which reward sustained, developing work.

Keeping the project developing

The objectives reward investigation and experimentation that are "sustained", and the hardest part of a long project is keeping it developing all the way through. Many projects start strongly, then stall or coast: the candidate runs out of next steps, or re-makes their best piece, or jumps to an outcome too early. A top-band project instead keeps generating next steps, so it deepens from start to end. The line of enquiry is what makes this possible: each stage raises a new question.

Purposeful experimentation that feeds the enquiry

Experimentation is the engine of development, but only when it is purposeful, when it feeds the enquiry rather than wandering. Each experiment should follow from the last and raise the next question: testing how to capture the movement of water leads to testing the light on it, then the threat of it. This is the difference between experimentation that develops the project and random sampling that does not, and it links directly to AO2's "reviewing and refining".

Avoiding the three traps

Naming the traps helps you avoid them.

• Stalling: running out of ideas and producing filler. The fix is to return to the line of enquiry and the next question it raises, or to bring in a new contextual source or subject.
• Repetition: re-making your best piece because it worked. The fix is to ask what the successful piece revealed and what to try next, not to reproduce it.
• Premature resolution: rushing to a final outcome too early. The fix is to develop the enquiry first, so the outcome resolves a developed investigation, not a shallow one.

Why sustained development reaches the top

The top bands of every objective reward "sustained" work, and depth comes from development over time, not from a single strong piece or a large quantity of similar ones. A project that deepens to the end evidences all four objectives at depth, because each is pursued and refined throughout. This is why sustaining development is the most reliable route to the top bands, and why stalling, repetition and premature resolution, however much they fill pages, cap the marks.

Try this

Q1. Name the three traps that stall a project's development. [Knowledge recall]

• Cue. Stalling (running out of ideas and producing filler), repetition (re-making a successful piece or adding variations that advance nothing), and premature resolution (jumping to a final outcome before the enquiry is developed).

Q2. Explain the difference between development and repetition, and why it matters for the marks. [Short explanation]

• Cue. Development moves the enquiry forward (each piece tries something new, refines an idea, or responds to the last), so the project deepens; repetition re-makes a successful piece or adds nothing new, so the project marks time; the objectives reward sustained development, not quantity, so repetition fills pages without lifting the marks while development reaches the top bands.
