Mathematics Assessment for Learning (AfL) Tool

Text reads "Catalytics" with icons of a pie chart segment, compass, plus sign, and "alytics" in blue font.

CATalytics is a computerised adaptive test which assesses Primary 5 and Primary 6 students’ proficiency in Standard Mathematics, based on the learning outcomes in the MOE Primary School Mathematics syllabus.

CATalytics is designed to assess how well a student has achieved the learning outcomes for a topic for his/her grade level. It is customised to the student’s ability with items chosen such that the test is age appropriate without being too challenging. The student’s performance is dependent on the difficulty of the items he/she has attempted.

CATalytics is currently offered in 4 topics:
1. Decimals
2. Fractions
3. Geometry
4. Measurement and Area & Volume

Each topical test consists of 30 multiple choice questions. Students are given 1 hour to complete each test.

Schools can choose the number of topics they would like to sign up for. If a school signs up for 4 topics, each student will take 4 topical tests.

CATalytics for Teaching and Learning

As a diagnostic tool, CATalytics' data and reports provide teachers with targeted insights about students' prior knowledge and learning gaps. Teachers can then develop focused remediation strategies and prepare appropriate resources for effective intervention.

Here is some feedback from teachers on how they have used CATalytics reports to enhance their teaching and learning.

A colorful infographic about teachers' feedback on CATalytics, highlighting its benefits for identifying and addressing learning gaps.

CATalytics Reports

The CATalytics reports comprise:
1. Group Profile Report (by school and class)
2. Student Profile Report
3. Profile Descriptors
4. Common Error Analysis

They provide information on the learning outcomes that students can manage, can partially manage, and cannot manage.
