Chart that shows reliability of IELTS writing task 2 scoring using UpScore.ai

Introduction

Can AI help with IELTS? The question of whether AI can assist with IELTS is frequently raised on platforms such as Reddit and YouTube. We firmly believe that AI can be a valuable tool for IELTS preparation, provided it is used correctly.

At UpScore.ai, we offer an AI-based approach to traditional services commonly known as "IELTS essay correction service" or "IELTS writing grading service." Our tool offers automatic, fast, and detailed feedback on IELTS essays, providing an accessible alternative to human evaluators.

The UpScore.ai Tool Explained

Our AI tool uses a combination of Natural Language Processing (NLP) and Machine Learning (ML) techniques to evaluate IELTS essays. It doesn't just look at grammar and vocabulary but also considers more complex elements such as coherence, cohesion, task achievement, and lexical resource—criteria that are part of the official IELTS Writing Task 2 evaluation.

We acknowledge the skepticism surrounding AI's grading capabilities. After all, grading involves a nuanced understanding of language that goes beyond mere syntax and grammar. To address these concerns, we conducted a benchmarking exercise comparing our tool to official IELTS grades.

Benchmarked Against Official Grading

For this purpose, we utilized a range of sample essays from bands 4 to 9, which are available on the ielts.org website. We evaluated each essay using UpScore.ai and compared the results to the evaluations provided by professional examiners from IELTS, which were included alongside the sample essays.

Natural Variation in IELTS Grading

It is important to remember that no grading process, whether conducted by humans or AI, can achieve perfect precision. Even human examiners may differ by a range of 0.5-1 band, and occasionally even by 1.5 bands, in their evaluations. While UpScore.ai's performance may not match the precision of a human examiner in every instance, it generally aligns closely with these variations. In the vast majority of cases, the results from UpScore.ai fall within the same grading range. This demonstrates that UpScore.ai is not only a viable option but also a practical and efficient tool for IELTS preparation, offering reliable feedback with an unmatched turnaround time.
