The most important term of selective preparation isn't Year 6 Term 1

Most families treat Year 6 Term 1 as the serious part. The test is May. That's when the tutoring hours go up, the practice tests multiply, and the household stress peaks.
It makes sense as a mental model. The test is close, the stakes feel real, and doing more feels like doing something useful.
The problem is that by Year 6 Term 1, the meaningful decisions have already been made.
What actually determines the result
Selective placement is the product of 18 months of preparation, not 10 weeks of it. A child who arrives at Year 6 Term 1 with genuine fluency in mathematical reasoning, a reading habit that's been running for a year, and 30 or 40 pieces of writing practice behind them is in a completely different position from a child who arrives having done a lot of practice tests but skipped the slow, unglamorous groundwork.
You can't compress the groundwork. That's the thing families find out too late.
Writing is the clearest example. It's the only selective component with no OC equivalent — there's no multiple-choice safety net — and it improves slowly, through regular practice and feedback over many months. A child who starts writing in Year 5 Term 1 has a year of small improvements compounding by the time they sit the test. A child who starts in Year 6 Term 1 has ten weeks. The gap between those two children on test day is not small.
One thing worth saying clearly: no parent should be expected to design all of this themselves. Planning all of the following is unreasonable:
- introducing a writing curriculum
- spotting the gaps
- assessing writing skills on a per piece basis
- judging when to move on to next skill level
The right tool handles the sequencing and shows your child exactly what to focus on. Your job is simpler and more important: protect the routine, keep the mood calm, and keep showing up. The plan handles the what and the when.
So which term actually matters most?
Year 5 Term 1.
Not because it's the most intense — it shouldn't be. But because it's when the habits that determine everything else either get established or don't.
There's also a reason not to rush into serious content before then. Selective material is pitched at Year 6 level. A child coming out of the Year 4 OC test simply hasn't covered the underlying schoolwork yet, and drilling Year 6 content too early is inefficient and demoralising rather than a head start. The child grows into much of it naturally over Year 5. The summer after OC results is for light diagnostics, re-establishing a routine, and starting to write small pieces. And by small, we mean starting with sentences only.
A child who starts writing in small pieces in Year 5 Term 1, builds a weekly routine across all four components, and treats mental maths fluency as something to develop steadily rather than cram later. That child has a 12-month head start on the one who waits until Year 6 to get serious.
Year 5 Term 1 is also when it's still possible to start gently. There's no looming deadline and no pressure to perform. It's the easiest possible time to build a habit, which is what makes selective preparation calm, rather than hectic.
What Year 6 Term 1 should actually be for
Term 1 is consolidation, but not yet the finish line. If there are still gaps to close or writing genres to strengthen, there's still time to work on them through this term. The test is months away, not weeks.
What changes is the final month. About four weeks out from the test, stop introducing anything new and switch entirely to light review. The goal is to arrive on test day rested, familiar, and calm, not exhausted from a last-minute push.
Consistent, calm, preparation beats stress-cramming every time. It’s not just good for your child, but for the entire family.
