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.

PTE Academic 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 Pearson’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.

Pearson 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 Pearson’s Ordinate technology

The spoken portion of PTE Academic is automatically scored using Pearson’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 Pearson’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.

What aspects of English does PTE Academic assess?

Managers and HR professionals have a global workforce at their fingertips – and now, nearly 50% of organizations plan to let employees work from home. This makes adopting a secure English language test for employment more important than ever.

An online English test enables organizations to assess candidates’ language proficiency from anywhere in the world, screen more applicants, and standardize the hiring process. They also help HR professionals and managers to save time – ensuring only people with the right language skills advance to the interview stage.

But how can employers be certain these tests are safe? And how easy is it for people to cheat? In this article, we’ll explore a few of the top security concerns we hear, and share what features make online language tests secure.

What is an online English test?

An online English test measures how well a job applicant can communicate in English, focusing on speaking, listening, reading and writing skills. They also assess a candidate’s specific English for business skills – for example, how clearly someone can communicate on the phone with clients, or understand what is being said during a conference call.

Online tests can be taken in a controlled environment – in a testing center with in-person proctors – but also from a job applicant’s personal computer or mobile phone at home. When tests are taken at home, they can be made more secure using virtual proctors or powerful AI monitoring technology.

Cheating, grading and data security

When many people think of taking a language test, they imagine the traditional way: students in a large testing center scribbling away with pen and paper. No mobile phones are allowed, and if test-takers are caught cheating, they’ll be flagged by a proctor walking around the room.

So when managers or HR professionals consider the option of an online English test – taken digitally and often without human supervision – it’s no surprise that many have questions about security. Let’s take a look at some common concerns:

Is cheating a problem?

A large number of test takers admit to cheating on their tests. According to research by the International Center for Academic Integrity, 68% of undergraduate students say they’ve cheated on a writing assignment or test, while 43% of graduate students say they have.

But how easy is it to cheat during a Versant test?

The truth is, not very. With Versant, exam cheating is actually quite difficult, and test takers would have to outsmart a range of AI monitoring technologies.

If a verified photo is uploaded to the platform, HirePro’s face recognition technology can compare the live test taker with it. This ensures test takers are who they say they are, and haven’t asked someone else to sit the exam for them. It is the institution’s responsibility to verify the original photo.

And since Versant tests are monitored using specialized AI algorithms – without a human present – even the slightest suspicious behaviors are flagged for review. For example, Versant notices if a different face appears in the video, or if the camera goes dark. With video monitoring, our platform also flags if the test taker moves from the camera, or looks away multiple times. And we’ll see if someone changes tabs on their computer.

Finally, the entire test is recorded. When suspicious behavior arises, HR professionals will decide whether to accept or reject the results – or have the candidate retake the test.

Are scores accurate?

We’ve all had frustrating experiences with AI. Chatbots don’t always understand what we’re trying to say, and speech recognition technology sometimes isn’t up to par. This leaves many wondering if they should trust AI to grade high-stakes tests – especially when the results could be the difference between someone getting the job, or not.

Versant uses patented AI technology to grade tests that are trained and optimized for evaluating English language proficiency. It evaluates speaking, listening, reading, writing, and even intelligibility.

Our AI is trained using thousands of fluent and second-language English speakers. With these models, we’re able to not only evaluate how someone should be assessed but also understand when they’ve mispronounced words or have made another mistake. Using all this information, a candidate’s final score is evaluated based on more than 2000 data points.

Do online tests follow GDPR standards?

HR professionals and managers deal with sensitive personal information every day. This includes each job applicant’s name, full address, date of birth, and sometimes even their social security number. The HR tools they implement therefore must also keep this data secure.

Most importantly, it must follow GDPR standards. The data must be gathered with consent and protected from exploitation. With Versant, test-taker data is securely stored and follows all GDPR guidelines.

All our data is encrypted at rest and in transmission. Versant assessment data is stored in the US and HirePro, our remote monitoring partner, stores the proctoring data in either Singapore or Europe, depending on customer needs. Both systems are GDPR compliant.

Versant: a secure English language test

The Versant automated language test is powered by patented AI technology to ensure the most accurate results for test takers and employers alike. Even better, our remote testing lets HR professionals securely and efficiently assess candidates worldwide, 24/7 – and recruit top global talent to help more companies scale.

As with all tests, adequate preparation is crucial. For many aspiring migrants needing to take an English test, it may have been several years since they took an official exam. Knowing how to prepare effectively and what to expect on the day are key when it comes to securing a successful outcome. Use these five exam preparation tips below to improve your English test results.

1. Familiarise yourself with the type of test questions you will be asked and know what to expect on the day

The official guides published by the testing bodies are an excellent source of information to help you fast-track your learning. They offer materials that replicate the real test questions as well as guidance and strategies for dealing with every task set. Taking a practice test in exam-like conditions helps to improve time management skills and set realistic expectations on your potential performance.

As with all high-stakes tests, security arrangements at the test center are strict. Test takers need to prove their identity via a passport or similarly approved document, so it’s a good idea to arrive at least 30 minutes before the test time and have your documents to hand.

2. Give yourself enough time by setting clear, measurable and achievable goals. This will help keep your motivation up and your end goal in sight

Start with a detailed understanding of your current English proficiency. That makes it easier to focus on any weaker areas ahead of taking the test and plan how long you’ll need to study for to bring your skills up to the required level.

3. Seek English instruction that works for you and matches your specific needs and learning goals

Coursebooks are a good option if you have a little more time to study in the run-up to the test. A rigorous preparation course structure will take you through a series of normally class-based lessons designed to prepare you for the test. Sometimes, however, the best way to prepare for a test is to join a class and receive tuition face-to-face. There is a multitude of courses and they offer class-based or individual tuition, from intensive week-long courses to six-month programs to help brush up on your English skills.

4. Choose quality materials that are at the right level for you – they should stretch you a bit to help you progress so you stay motivated

Digital learning can be very useful, providing opportunities to study at a time that suits and giving lots of feedback opportunities. Many test-takers take advantage of the large amount of free preparation material that includes everything from print and digital course guides to practice tests. A huge amount of information is also posted on YouTube, including tutorials and advice covering the range of different tests on offer.

5. Be persistent – keep practicing at every opportunity

Make the most of those spare minutes to practice your skills. Every workday includes a little downtime so try to incorporate a few short 5 or 10 minute practice activities each day to keep building your knowledge.

IELTS has long been the standardized test approved by the Australian government and the test of choice for visa applicants both for work and study. Since November 2014, in an effort to make it more convenient for applicants, the DIBP has approved a number of additional tests that can be used as proof of English language skills, including TOEFL iBT, Cambridge English Advanced (CAE) and the Pearson Test of English Academic (PTE Academic).

Bonus tip just for PTE Academic test takers

PTE Academic offers a wide range of free and paid materials online that help test takers prepare for their migration visa English test. Of particular note is the Scored Practice Test which gives test takers an indicative score – so they know how close they are to their goal.
