Research has shown that automated scoring can give more reliable and objective results than human examiners when evaluating a person’s mastery of English. This is because an automated scoring system is impartial, unlike humans, who can be influenced by irrelevant factors such as a test taker’s appearance or body language. Additionally, automated scoring treats regional accents equally, unlike human examiners who may favor accents they are more familiar with. Automated scoring also allows individual features of a spoken or written test question response to be analyzed independent of one another, so that a weakness in one area of language does not affect the scoring of other areas.

was created in response to the demand for a more accurate, objective, secure and relevant test of English. Our automated scoring system is a central feature of the test, and vital to ensuring the delivery of accurate, objective and relevant results – no matter who the test-taker is or where the test is taken.

Development and validation of the scoring system to ensure accuracy

PTE Academic’s automated scoring system was developed after extensive research and field testing. A prototype test was developed and administered to a sample of more than 10,000 test takers from 158 different countries, speaking 126 different native languages. This data was collected and used to train the automated scoring engines for both the written and spoken PTE Academic items.

To do this, multiple trained human markers assess each answer. Those results are used as the training material for machine learning algorithms, similar to those used by systems like Google Search or Apple’s Siri. The model makes initial guesses as to the scores each response should get, then consults the actual scores to see well how it did, adjusts itself in a few directions, then goes through the training set over and over again, adjusting and improving until it arrives at a maximally correct solution – a solution that ideally gets very close to predicting the set of human ratings.

Once trained up and performing at a high level, this model is used as a marking algorithm, able to score new responses just like human markers would. Correlations between scores given by this system and trained human markers are quite high. The standard error of measurement between app’s system and a human rater is less than that between one human rater and another – in other words, the machine scores are more accurate than those given by a pair of human raters, because much of the bias and unreliability has been squeezed out of them. In general, you can think of a machine scoring system as one that takes the best stuff out of human ratings, then acts like an idealized human marker.

app conducts scoring validation studies to ensure that the machine scores are consistently comparable to ratings given by skilled human raters. Here, a new set of test-taker responses (never seen by the machine) are scored by both human raters and by the automated scoring system. Research has demonstrated that the automated scoring technology underlying PTE Academic produces scores comparable to those obtained from careful human experts. This means that the automated system “acts” like a human rater when assessing test takers’ language skills, but does so with a machine's precision, consistency and objectivity.

Scoring speaking responses with app’s Ordinate technology

The spoken portion of PTE Academic is automatically scored using app’s Ordinate technology. Ordinate technology results from years of research in speech recognition, statistical modeling, linguistics and testing theory. The technology uses a proprietary speech processing system that is specifically designed to analyze and automatically score speech from fluent and second-language English speakers. The Ordinate scoring system collects hundreds of pieces of information from the test takers’ spoken responses in addition to just the words, such as pace, timing and rhythm, as well as the power of their voice, emphasis, intonation and accuracy of pronunciation. It is trained to recognize even somewhat mispronounced words, and quickly evaluates the content, relevance and coherence of the response. In particular, the meaning of the spoken response is evaluated, making it possible for these models to assess whether or not what was said deserves a high score.

Scoring writing responses with Intelligent Essay Assessor™ (IEA)

The written portion of PTE Academic is scored using the Intelligent Essay Assessor™ (IEA), an automated scoring tool powered by app’s state-of-the-art Knowledge Analysis Technologies™ (KAT) engine. Based on more than 20 years of research and development, the KAT engine automatically evaluates the meaning of text, such as an essay written by a student in response to a particular prompt. The KAT engine evaluates writing as accurately as skilled human raters using a proprietary application of the mathematical approach known as Latent Semantic Analysis (LSA). LSA evaluates the meaning of language by analyzing large bodies of relevant text and their meanings. Therefore, using LSA, the KAT engine can understand the meaning of text much like a human.

His work focuses on integrating AI into education to support personalized and flexible learning for teachers and learners.

    For many adult learners, mastering English isn’t just about gaining a new skill—it’s about unlocking opportunities in work, family and social spheres. But juggling English lessons alongside work, family obligations and social commitments is a challenge that can feel overwhelming.

    This guide explores the unique challenges adult learners face and how educators can support them with empathy, flexibility and effective strategies.

    The challenges of learning English as an adult

    Meet Le, a 35-year-old Vietnamese project manager who dreams of working for an international company. With a demanding full-time job and two young children, finding time for English lessons feels impossible. Missing classes and struggling to complete assignments leads to frustration and self-doubt—an all-too-common experience among adult learners.

    Many adults face similar challenges:

    • Balancing work, family and personal commitments leaves little time and energy for study.
    • Fatigue after a long day makes it difficult to concentrate or retain information.
    • Progress feels slow, which can be demotivating.

    Without practical support, the goal of English proficiency can seem out of reach.

    Strategies for overcoming challenges

    1. Setting SMART Goals

    Educators can guide learners to set Specific, Measurable, Achievable, Relevant, and Time-bound (SMART) goals. Breaking down larger objectives into small, measurable milestones gives learners a sense of achievement. For example, app’s Global Scale of English (GSE) provides actionable “Can-do” statements, such as:

    • Reading (GSE 37/CEFR A2+): Can understand simple personal emails.
    • Speaking (GSE 44/CEFR B1): Can give a short talk with visual support.

    These manageable goals create motivation and help learners like Le stay focused without feeling overwhelmed.

    2. Offering flexible learning options

    Flexibility is key for adult learners. Teachers can adopt strategies such as:

    • Modular lessons that can be completed in short sessions.
    • Micro-learning, including 10-minute daily practices using apps or quick grammar exercises.

    For learners like Le, micro-learning can easily be integrated into a work commute or lunch break.

    3. Blending learning with real-world scenarios

    Teaching English through practical, real-life contexts makes lessons more relevant and efficient. Using authentic materials like emails, meeting notes, or presentations mirrors learners’ daily lives and creates immediate applications for their new skills. For instance:

    • Help learners role-play workplace conversations.
    • Develop speaking proficiency for social interactions or workplace scenarios.

    This approach saves time and reinforces the usefulness of learning English, keeping learners motivated.

    4. Encouraging weekly reflection

    Reflection allows learners to monitor their progress, stay motivated and adapt their strategies. Teachers can:

    • Encourage learners to set weekly goals (e.g., learning new business vocabulary or practicing pronunciation for 15 minutes daily).
    • Use reflection journals to track achievements, identify challenges and adjust learning plans.

    This habit reinforces a growth mindset, helping learners make consistent progress amidst their busy schedules.

    Implementing the strategies

    Here’s how educators can apply these strategies effectively:

    1. Assess and set goals

    Work with learners to set realistic, measurable goals based on their personal motivations and schedules.

    2. Create flexible study plans

    Develop personalized study schedules that incorporate modular lessons and micro-learning techniques.

    3. Use authentic materials

    Include sample emails, presentations, or conversations that align with the learner’s work or life situations, making lessons more practical.

    4. Encourage accountability

    Implement tools like reflective journals or digital reminders to help learners stay on track and see their progress.

    5. Leverage personalized AI tools

    Use AI-powered tools to recommend tailored exercises, provide instant feedback and enable targeted practice in learners’ focus areas.

    Why It matters

    English proficiency opens doors to better job opportunities, stronger social connections and enriched personal growth. By providing empathetic and flexible support, teachers empower learners to achieve their goals without compromising their work-life balance.
    For educators seeking further resources, app’s GSE framework offers valuable tools to help adult learners succeed. Teachers can use these aids to track progress and personalize lessons for maximum impact.
