The Global Scale of English explained: making progress measurable

What is the Global Scale of English (GSE)?

The Global Scale of English, or GSE, is a scale for English proficiency developed by Pearson. At its core is a numerical scale from 10 to 90. Each score range is linked to learning objectives describing what a person at that level can do. It is aligned with the CEFR but measures in finer steps.

According to Pearson, these learning objectives were developed in research involving more than 6,000 teaching and learning experts from over 50 countries and calibrated to the scale.

The GSE does not replace the Common European Framework of Reference for Languages (CEFR); it is aligned with it and divides it more finely. Where the CEFR has six broad levels from A1 to C2, the GSE shows movement within those levels. That makes it interesting for companies that want to know not just whether someone is “B1”, but whether anything has changed after three months of training.

In my work as Head of Studies at choices®, the GSE has therefore become the backbone of our language audit for companies. Not because yet another scale adds value in itself, but because it makes it possible to answer a question that management will sooner or later ask: what exactly has the training achieved?

GSE and CEFR: the difference explained simply

The CEFR is the European standard for language levels, and it will remain so. HR departments, universities and public authorities in Germany, Austria and Switzerland work with A1 to C2. The GSE is not a competitor but a measuring tool with a finer resolution, useful wherever you need to see progress within a single CEFR level.

An image I like to use in workshops with HR teams: the CEFR is the map showing the major cities, and the GSE is the satnav that also shows you the miles in between. For job profiles, the map is enough. If you want to steer learning progress, you need the satnav. You can read more about the six levels themselves in our article on CEFR levels A1 to C2.

Understanding GSE scores: what do 30, 50 or 70 mean?

On the GSE, 30 stands for pre-intermediate, roughly simple emails and small talk with some effort; 50 for high intermediate, handling customer conversations and explaining problems; and 70 for advanced, arguing spontaneously and expressing nuance. The range names come from Pearson; how they translate into working life is a practical interpretation.

Pearson groups the scale into broad ranges in its own guide to GSE scores. This grouping helps you communicate test results clearly to employees and managers.

The right-hand column is my own practical interpretation, not an official description. But it shows what matters: the number on its own is abstract. Only by linking it to situations in your organisation does it become tangible for managers.

Why the Global Scale of English is so useful for companies

The GSE makes visible the progress that gets lost in the CEFR: a person can stay at B1 according to the CEFR and still rise from 48 to 53 points on the GSE. For companies, this brings three advantages: finer resolution, comparability across groups, sites and intakes, and more credible data when an independent test does the measuring.

Adults learn in phases. After a fast start at the lower levels, progress at B1 and B2 becomes slower. This is where the reporting of many training programmes falls down: after six months, the report says “B1” again, and the finance team gets the impression that nothing has happened.

In my article for Pearson Languages, I described the example of a person who stays at B1 on the CEFR but rises from 48 to 53 points on the GSE. For adult learners, that is a real achievement. Without the finer scale, it would remain invisible.

Three advantages I see again and again in practice

1. Granularity: small steps forward become visible, and so do plateaus. If a group stagnates for three months, that is a signal to adjust the content or format.
2. Comparability: groups, sites and intakes can be compared on the same scale. This makes budget decisions considerably easier.
3. Credibility: if progress is measured with an independent, GSE-based test, the training provider is not marking its own homework. I consider this conflict of interest one of the biggest unsolved problems in corporate language training.

On that last point, I have a clear opinion: a provider that assesses its own learners, teaches them and then certifies its own success is not delivering reliable data. It is delivering marketing. Independent measurement is uncomfortable, but in the end it also protects the budget.

Using the GSE in a language audit: baseline, mid-point, final result

In a language audit, the GSE is used three times: as an independent baseline before the course starts, combined with an interview; as a mid-point test after three to six months to show whether you are on track; and as a final test at the end of the programme, which forms the basis for reporting to HR and management.

The GSE only delivers its benefits if it is used systematically. The choices® methodology team works with a simple three-step approach:

1. Baseline before the course starts: an independent test, complemented by an interview. The result feeds into how groups are formed. Our article on language placement tests for companies describes how this works organisationally.
2. Mid-point test after three to six months: it shows whether the direction is right. If necessary, groups are reorganised or content is sharpened at this stage.
3. Final test at the end of the programme: the basis for reporting to HR and management, and for deciding on the next phase.

Between the tests, short, regular signals keep coming in: attendance, feedback after lessons, observations from line managers. I like to call them pulse checks. They do not replace the GSE measurement, but they ensure you do not discover only after six months that something has gone wrong.

What a realistic GSE gain looks like

How many points a team gains over a period depends mainly on the starting level and the amount of learning time per week. Progress is faster at lower levels and slower at B2 and C1. That is why I advise against writing rigid point targets into contracts. Target ranges, agreed jointly after the baseline, make more sense.

KPIs for language training with the GSE: a sample set

A proven KPI set built on the GSE covers six areas: participation with about 75% attendance, learning with a median gain of around 4 to 5 GSE points, application at work, experience with satisfaction of about 4.5 out of 5, business impact with 10 to 15% less rework, and continuation with at least 70% re-enrolment.

In the second part of my series for Pearson Languages, I described benchmarks that have proved themselves in programmes. I deliberately call them signposts rather than a straitjacket: they need to be adapted to the role, level and company culture.

Our article on language training reporting for HR shows how to turn these figures into a report that management will actually read. And our sample ROI calculation for Business English explains how to translate them into euros. If you read Polish, our article The Global Scale of English at a glance (in Polish) offers a further introduction.

Using GSE learning objectives in Business English training

The second major benefit of the GSE lies in planning rather than measurement. Because each score range is linked to learning objectives, you can build a course around exactly the next steps a group needs. Instead of “we’re doing Business English at B1”, the brief becomes: “this group works on the objectives between its current score and its target range”.

What this looks like in practice

For a purchasing department with a baseline median in the mid-forties, a quarterly plan might focus on the following areas. The wording is our own practical examples, not original descriptors:

• explaining delivery delays in a phone call and suggesting alternatives
• responding to a price adjustment in an email, politely but firmly
• asking for clarification in a video call without interrupting the flow of the conversation
• writing a short summary of a supplier meeting for the team

The advantage is that learners can see what they are working on, and managers can observe whether these very situations go better in everyday work. The learning objectives become the bridge between test score and working reality. That bridge is missing in many programmes, which measure levels but never say concretely what should change in day-to-day work.

The limits of the GSE: three misunderstandings from practice

The GSE is a powerful measuring tool, but three misunderstandings repeatedly lead to unrealistic expectations. It is not a curriculum, because only a language needs analysis shows what a team needs. A point at A2 represents less learning effort than a point at C1. And a high test score does not prove that someone communicates confidently with customers.

1. “The GSE is a curriculum.”

No. The GSE learning objectives describe what is possible at a given level. What your sales team in Nuremberg or your purchasing team in Vienna actually needs only becomes clear from a language needs analysis. The scale measures; the needs analysis steers.

2. “A point is a point.”

Five points at A2 are not the same as five points at C1. At higher levels, each point represents considerably more learning effort. If you compare groups with different starting levels, you need to take this into account; otherwise the beginners’ group will always look better.

3. “A high test score means the person communicates well.”

A test measures a sample of language behaviour under test conditions. Whether someone stays composed in a customer conversation also shows in observations at work. That is why we always combine GSE data with feedback from managers and learners. Figures without context lead to poor decisions.

The GSE, certificates and the next step for your organisation

Internal GSE measurement and external certificates complement each other. Measurement steers the training, while a certificate makes the result visible to the outside world and motivates learners. Pearson links the two: the Pearson English International Certificate is aligned with the GSE. choices® does not run exams, but prepares learners for them in targeted exam preparation.

You can read more in our article on the Pearson English International Certificate.

How to get started

• Decide for which roles finer progress measurement makes sense.
• Agree an independent baseline measurement with your provider.
• Define a few KPIs per area instead of an overloaded dashboard.
• Plan the mid-point and final tests at the kick-off stage.

If you would like to know how GSE-based measurement fits into your programme, the choices® language audit is the right place to start. For the implementation that follows, Business English courses in small groups or one-to-one are available as part of our range of language courses for companies. The question of how to go about measuring the success of language training is also closely linked to your choice of scale.
