GL Assessment Guide for Parents: Understanding Your Child’s Progress in British Schools

When your child studies in a British international school, you may come across reports filled with unfamiliar terms, scores, and benchmarks. For many families, especially those new to the British curriculum, understanding how academic progress is measured can feel confusing at first. One of the most widely used systems in international schools is GL Assessment. Designed to provide a clear and standardised way of tracking student performance, GL assessments help schools, students, and parents gain meaningful insights into learning progress over time.

This guide is designed to help you understand what GL Assessment is, how it works, and how you can interpret your child’s results with confidence.

Key Takeaways

• What They Are: GL Progress Tests are standardised assessments in English, Maths, and Science that benchmark a child’s performance against the national average for their age group.
• Purpose: They are not pass/fail exams. Their goal is to track academic progress over time and identify a child’s strengths and areas needing further support.
• How Schools Use Them: Educators use the detailed data to personalise teaching, ensuring each student receives the right level of challenge and support.
• Understanding Results: The most important metric is the Standard Age Score (SAS), where 100 is the national average. This score provides a clear picture of how your child is performing relative to their peers.

What Is GL Assessment?

GL Assessment is a UK-based provider of standardised assessments used by schools worldwide to measure student progress.

Unlike traditional classroom tests, which often focus on recently taught content, GL assessments evaluate broader skills and understanding. This allows schools to track development over time and compare performance with students of the same age globally.

For parents, this provides a clearer and more objective picture of how their child is progressing within an international academic framework.

What Are GL Progress Tests?

One of the most widely used tools developed by GL Assessment is the GL Progress Test series.

These tests are designed to track how students develop over time in key subject areas such as English, mathematics, and science. They are typically taken at regular intervals, allowing teachers to build a reliable and consistent understanding of each student’s academic journey.

GL Progress Tests are particularly valuable because they:

• Compare a student’s performance with a large international cohort
• Track improvement year by year
• Highlight long-term trends rather than isolated results

For parents, this means that the results are not just about how your child performed on a single test. Instead, they provide insight into how your child is progressing over time, which is far more meaningful.

Why Do Schools Use GL Assessments?

The real value of GL Progress Tests lies in the data they provide. For schools, these results are a powerful tool for improving teaching and learning outcomes for every child.

1. Personalising Learning: The detailed reports break down performance by topic. A teacher can see if a student excels in ‘Number’ but needs support in ‘Geometry’. This allows for targeted interventions and extension activities, ensuring every child is appropriately challenged.
2. Tracking Progress Over Time: By administering the tests annually, schools can build a clear picture of a child’s academic trajectory. This helps identify consistent growth or flag any areas where a student might be falling behind, allowing for early intervention.
3. Informing Teaching Strategy: School leaders and teachers analyse cohort-level data to identify trends. If many students struggle with a specific scientific concept, the curriculum or teaching approach for that topic can be refined, benefiting the entire year group.
4. Facilitating Meaningful Conversations: At The ABC International School (ABCIS), these results form the basis of productive conversations with parents. They allow us to discuss a child’s specific needs and collaboratively set achievable goals for their future development.

What Do GL Assessments Measure?

GL assessments are designed to evaluate a range of core academic skills. Rather than focusing on memorisation, they assess how well students can apply their knowledge.

1. English

Students are assessed on key literacy skills, including:

• Reading comprehension: literal meaning, inference and deduction, vocabulary in context and analysis of language.
• Technical English skills: Spelling, punctuation and grammar.

These skills are essential not only for English lessons but also for learning across all subjects.

2. Mathematics

The mathematics component focuses on:

• Numerical understanding
• Problem-solving abilities
• Application of mathematical concepts such as Algebra, Geometry, Statistics and measurements.

This helps schools understand how students approach mathematical thinking, not just whether they arrive at the correct answer.

3. Reasoning Skills

GL assessments often include reasoning sections, such as:

• Verbal reasoning
• Non-verbal reasoning
• Spatial awareness

4. Scientific Skills

The science component focuses on:

• Biology
• Chemistry
• Physics
• How to work scientifically using skills such as data analysis, planning experiments and evaluating experiments.

These areas measure how students think, analyse patterns, and solve unfamiliar problems. They provide valuable insight into a child’s cognitive development and learning potential.

What Subjects and Skills Do GL Progress Tests Cover?

The tests provide a detailed analysis of a student’s abilities across three crucial curriculum areas. Each test is carefully constructed to assess both knowledge and the application of that knowledge.

Progress Test in English (PTE)

The PTE assesses key literacy skills that are fundamental to learning across all subjects. The test is broken down into two main sections:

• Reading Comprehension: This measures a student’s ability to understand, interpret, and make inferences from texts. It assesses skills from simple information retrieval to analysing an author’s intent.
• Spelling, Punctuation, and Grammar: This section evaluates a student’s technical accuracy in writing, which is crucial for clear communication.

Progress Test in Maths (PTM)

The PTM covers the full mathematics curriculum, focusing on both conceptual understanding and problem-solving skills. It assesses two key domains:

• Mathematical Content Knowledge: This tests fluency in core topics such as number and algebra, geometry, measures, and statistics.
• Mathematical Reasoning: This requires students to apply their knowledge to solve multi-step problems and think logically in unfamiliar contexts.

Progress Test in Science (PTS)

The PTS measures a student’s scientific knowledge and, importantly, their ability to think and work scientifically. It covers the three main scientific disciplines:

• Biology: Topics related to living organisms, life cycles, and ecosystems.
• Chemistry: Focuses on the properties of materials and chemical reactions.
• Physics: Concepts such as forces, energy, light, and sound.
• Working Scientifically: This crucial component assesses skills like planning experiments, evaluating evidence, and interpreting data.

How to Understand Your Child’s GL Assessment Results

When you receive your child’s report, it’s easy to get lost in the numbers. The key is to focus on the Standard Age Score (SAS), as this is the most accurate measure of their performance.

The SAS compares your child’s score with the results of a nationally representative sample of students of the same age. Here’s a simple guide to what the scores mean:

• SAS of 100: This is the exact national average.
• SAS between 85 and 115: This range is considered the ‘average’ band, where the majority of students will score.
• SAS above 115: This indicates high attainment for their age group.
• SAS below 85: This suggests the student may require additional support to catch up with their peers.

Remember, the SAS is not a percentage. It is a benchmark. The goal is not to chase a high score but to understand your child’s learning profile. These tests are a starting point for a conversation with their teacher, who can provide the full context behind the numbers.

Understanding “Average”

The term “average” in standardised testing represents a wide range of performance. Being within the average range is a positive outcome and indicates that your child is developing as expected.

Progress over time is often more meaningful than whether a score is slightly above or below average.

How ABCIS Uses GL Assessments

At The ABC International School (ABCIS), assessments are part of a wider approach to supporting each student’s learning journey.

Within the Primary Curriculum, which covers Key Stage 1 and Key Stage 2, GL assessments help teachers understand how students are developing key skills in literacy, numeracy, and reasoning. (*) These insights support a nurturing environment where children can build confidence and strong academic foundations.

As students move into the Secondary Curriculum, which begins with Key Stage 3, assessments continue to play an important role in tracking progress. (*) At this stage, students are developing greater independence, and clear feedback helps them better understand their own learning.

At ABCIS, the focus is on:

• Encouraging steady progress over time
• Supporting individual learning needs
• Providing clear and constructive feedback to students and parents

Assessments are used as a tool to support development, not to create unnecessary pressure.

If you would like to learn more about how ABCIS supports students through both the Primary and Secondary Curriculum, you are warmly invited to get in touch with the admissions team or arrange a visit to the school. Speaking directly with staff and experiencing the learning environment can help you better understand how your child’s progress is nurtured and supported every step of the way.

How Parents Can Support Their Child

Understanding assessment results is only one part of the process. Your response as a parent can have a significant impact on your child’s confidence and motivation.

1. Focus on Progress

Rather than concentrating on a single score, consider how your child is improving over time. Consistent progress is a strong indicator of successful learning.

2. Encourage Positive Conversations

Talk to your child about their learning experiences. Simple questions such as:

• What did you enjoy learning recently?
• Which subjects do you find more challenging?

These conversations help build confidence and encourage reflection.

3. Avoid Comparisons

Children develop at different rates. Comparing your child’s results with others can create unnecessary pressure and does not reflect their individual learning journey.

4. Work with the School

Teachers can provide valuable context and guidance. If you have questions about your child’s results, discussing them with the school can help you better understand how to support your child.

Building Confidence Through Understanding

For many families, becoming familiar with assessment systems takes time. However, once you understand how GL assessments work, they become a helpful tool for supporting your child’s education.

Rather than focusing on individual numbers, it is useful to look at the broader picture. These assessments provide insights into progress, highlight areas of strength, and support meaningful conversations between parents, students, and teachers.

At The ABC International School (ABCIS), this approach is central to how learning is supported. By combining thoughtful assessment with a caring environment, the school aims to foster confidence, curiosity, and a lifelong interest in learning.
