Key Outcomes

1. CAT4 enables schools to not only identify their gifted students, but to differentiate within this group to inform support and development needs
2. The data provides insights across the ability spectrum, including SEND and EAL
3. The data also supports parental discussions and can help inform future curriculum and subject choices

Data-Driven Insight Transforms Gifted Student Identification at St Andrew’s

Founded in 1885, St Andrew’s Cathedral School is an independent Anglican co-educational day school located in the heart of Sydney’s central business district. With multiple campuses, the school welcomes around 1,450 students from Kindergarten to Year 12, forming a strong learning community that nurtures each student’s individual strengths. St Andrew’s offers both the Higher School Certificate (HSC) and the International Baccalaureate (IB) Programme.

Estee Stephenson was appointed Head of Gifted Education in 2019. One of her first priorities was to review how the school identified students for its gifted programme.

“When I joined, I inherited spreadsheets of data and quickly realised there was a disconnect between the identification measure we were using and what we were actually seeing in the classroom,” Estee explains. “The measure was based on achievement, not on ability, and was therefore not identifying gifted students in line with best practice.”
This prompted Estee to explore alternative approaches. She was recommended GL Education’s Cognitive Abilities Test (CAT4) – a tool designed to assess students’ developed abilities in four key areas known to impact learning and achievement: verbal, non-verbal, quantitative, and spatial reasoning.

CAT4 has since helped St Andrew’s identify high achievers, uncover students with untapped potential, and highlight those who may benefit from additional support in specific areas.

I trust CAT4 and the data it generates. I know that it’s valid. I know that it’s reliable. That is hugely important. I spent time putting together a discussion paper on best practice in gifted identification and submitted it to the senior executive team, who gave me the go-ahead to trial CAT4 on a sample of Year 9 students. This meant we could look at the reports and better understand what they would look like within our own context, with students we already knew. We found a strong correlation between the data CAT4 was giving us and our internal data, including MYP term scores, NAPLAN results, and other psychometric data we had on these students – which gave us confidence that CAT4 was a good fit for our needs.

Once we had established that CAT4 was what we needed, I put forward a proposal for it to be rolled out more widely, replacing our previous measure. This was signed off in December 2019, with a plan to begin testing in 2020. Due to the pandemic, this had to be postponed, but we completed our first round of testing in January 2021.

Benefitting the whole school

It soon became clear that the new assessment would be beneficial across the whole senior school, and could support all teaching and learning, not just the gifted programme. Estee explains:

What’s interesting is that this was a gifted problem – we didn’t know who our most gifted students were – but then going through the options and finding a solution, ended up being a solution for everybody. It’s not just for the gifted kids, it’s not just for the English as an Additional Language (EAL) kids, it’s for the whole school. We are now able to identify students who come to us with a learning support profile but who we can identify as gifted. Our previous measure was not able to do this as it was just based on performance. This is life changing for some students. For example, one student came to us last year with a hearing impairment, and no-one knew that the student was gifted. Through the CAT4 data we were able to identify this student’s potential and place them in the gifted classes last year and they aced them.”

The CAT4 data also helps discussions with parents. Estee explains:

In the past we have had parental complaints about class placements. Last year we didn’t have any complaints at all, meaning that our identification has improved and parents are reassured that we’re seeing what they see at home and we are making the appropriate placements.

Supporting the team in being responsive

The school uses CAT4 with every student as they enter Year 7, and also with everyone who joins the senior school at a later point. The previous test was only administered in Year 6, and if a student joined after that, then data wasn’t generated for them.

Estee outlines the benefits:

Now every student who is new to the school does the test, which means that we have data available on every senior school student.

St Andrew’s Cathedral School makes use of the IB and MYP indicators to determine if intervention services might be needed for underachieving students. Estee explains:

I had a student who scored high on CAT4 but the student has a learning disability and there was a disconnect with the student’s achievements. We realised that this student wasn’t receiving any accommodations, so learning support were able to intervene and arrange adjustments for the student’s assessments. The student’s achievement levels have improved, now that the accommodations are in place.

The team are now developing how the classroom teachers make use of the data. Estee explains:

My next focus is improving the data literacy of our classroom teachers. Our heads of department, heads of wellbeing, learning support and gifted team are all now well-versed in CAT4, so I plan to look further at supporting our teachers in exploring and making the most of the data for differentiation and planning.

Conclusion

The school has seen a huge improvement in their ability to identify and support their gifted students. Estee explains:

The difference in the gifted data now that we’re using CAT4 is enormous. Previously I’d just be able to identify a large group of students who were supposedly gifted, but I couldn’t dig deeper into that and untangle where they sit within the range of gifted abilities. Now with CAT4 I can put them into groups and provide service and acceleration to meet their needs. I trust CAT4 and the data it generates. I know that it’s valid. I know that it’s reliable. That is hugely important.

The process of implementation has also been positive. Estee explains:

The customer support that we’ve received has been extraordinary. People think that I’m some kind of CAT4 data guru, but the information I’ve got has been from all the excellent information provided through the GL Education website, through training videos, the detailed Strategies for Learning handbook and through customer support. If I have a question, then the GL team are always there to help. Schools are busy places, so there’s no time to take many weeks to answer a query. GL always get back to me with help and support rapidly, and that’s what I find so valuable.

The impact has been seen so clearly in the senior school, CAT4 has now been taken on in St Andrew’s Primary School, where colleagues are using it at key points in Years 4 and 6.
