Choosing three selective school preferences is not simply a matter of listing the schools with the strongest reputation. A good preference list should reflect the family’s genuine priorities, the student’s recent performance and the level of risk the family is prepared to accept.
The aim is not to predict one exact admission score. It is to create three meaningful choices at different competitive levels.
1. How the Three Preferences Work

Applicants may list up to three selective school preferences. These are generally placed in the order the student genuinely wishes to attend them.
If the student qualifies for an earlier preference, the later preferences are no longer available for consideration in the selection process. This means it usually makes little sense to place an easier school first and a more desirable school later. The first preference should be the school the family would choose first if all three were available.
2. Use Recent Performance, Not One Result
One Trial Test can be affected by question mix, concentration, health or an unusually strong or weak day. School choices should not be based on one high score or one disappointing result.
A more reliable starting point is the average of the student’s most recent five CTedu Trial Tests. Families should also look at the direction of the results:
- Is the student improving steadily?
- Are the scores stable?
- Does performance vary widely from test to test?
- Are all subjects reasonably balanced, or is one subject creating significant risk?
A stable average gives a better indication of the student’s current level than a single result.
3. A Practical Three-School Strategy
For many families, the following structure provides a useful starting point:
- First preference: a school slightly above the student’s current stable performance level.
- Second preference: a school broadly matched to the student’s recent average performance.
- Third preference: a school at a lower competitive level that the family would genuinely be willing to accept.
This is not a fixed formula. Some families may choose three ambitious preferences because they already have a strong local public school or private school alternative. Others may prefer a more conservative third preference because gaining a selective place is particularly important to them.
4. How Far Apart Should the Preferences Be?
A preference list only provides meaningful protection when the schools sit at genuinely different competitive levels. Three schools with similar estimated entry ranges may look like three choices, but they effectively carry almost the same admission risk.
Based on CTedu’s historical results, the performance gap between the most competitive selective schools and lower-entry fully selective schools can be around 20 CTedu Trial Test marks. The gap between the most competitive schools and some partially selective schools may exceed 30 marks.
These figures are broad historical references, not official cut-off scores or guarantees. School demand changes from year to year, and different students may perform differently in the official test.
The important point is that a real backup preference may need to sit noticeably below the first preference. Simply choosing three schools within the same narrow competitive band does not create much protection.
5. How to Judge Each School’s Competitive Level

Official result reports currently provide broad subject bands rather than a complete numerical score. However, offers are still determined by comparative performance, and historical offer patterns make it possible to estimate broad competitive ranges.
During preparation, families can use three main references:
- The CTedu Peak Climbing Chart.
- The student’s recent five-Test average and performance trend.
- CTedu’s previous annual Selective School Results Report.
The Peak Climbing Chart provides a visual indication of the schools broadly associated with the student’s current Trial Test level. The annual results report can show how school competitiveness appeared in the previous admission cycle.
Neither should be treated as a permanent official cut-off. They are planning tools that help families compare schools and create a sensible preference spread.
6. When to Spread the Preferences Further Apart
Families should consider a wider gap between preferences when:
- The student’s Trial Test scores fluctuate significantly.
- Performance drops sharply under time pressure.
- One subject remains noticeably weaker than the others.
- The family does not have a satisfactory alternative school.
When results are highly stable and the student has a strong alternative school, the family may be comfortable placing the three preferences closer together or choosing more ambitious options.
7. Consider the School, Not Only the Entry Level
A school is not automatically the right choice simply because it is more competitive.
Families should also consider:
- Travel time and daily transport.
- Whether the child prefers a boys’, girls’ or co-educational environment.
- The school culture and learning environment.
- The child’s willingness to attend the school.
- The effect of a long commute on sleep, homework and extracurricular activities.
8. How Backup Options Affect the Strategy
Families with a strong local public school, private school place or another satisfactory option can usually take more risk. They may decide that only certain selective schools would justify changing the child’s current pathway.
Families without a strong alternative may prefer a more conservative third preference. In that situation, it is especially important that the third school sits at a meaningfully lower competitive level than the first two.
9. Common Mistakes to Avoid
- Placing the most desired school below a less desired school.
- Choosing schools based on one unusually high Trial Test result.
- Selecting three schools from almost the same competitive range.
- Using a third preference that the family would not actually accept.
- Focusing only on entry difficulty and ignoring travel or school suitability.
- Treating last year’s estimated range as a guaranteed cut-off for the next year.
10. How CTedu Can Help
CTedu provides several tools that help families make a more informed decision.
- The Peak Climbing Chart shows the student’s current position in relation to different selective schools.
- The recent Trial Test average reduces the effect of one unusually strong or weak result.
- The performance trend shows whether the student is improving, stable or fluctuating.
- The annual Selective School Results Report provides updated historical evidence about school competitiveness and CTedu student outcomes.
These tools do not replace the family’s judgement. They provide a clearer evidence base for balancing ambition, realism and school suitability.
Final Thoughts
The best preference list is not necessarily the one containing the three highest-ranked schools. It is the one that reflects the student’s current level, the family’s genuine school preferences and an appropriate level of risk.
List schools in true preference order. Use several recent Trial Tests rather than one result. Make sure the preferences sit at meaningfully different competitive levels, especially when the third preference is intended as a backup.
