AI Grading Systems: Pros & Cons
Updated: Jul 24
In the digital age, technology has permeated every aspect of our lives, including education. One of the most intriguing advancements is the use of Artificial Intelligence (AI) in grading systems. This blog post aims to demystify AI grading systems, discussing their pros, cons, and impact on education.
Understanding AI Grading Systems
AI grading systems are advanced technologies that utilize artificial intelligence to evaluate and grade student work. They can handle a variety of assignments, from multiple-choice tests to short answer questions and even essays. These systems use machine learning algorithms to learn from a set of training data and then apply this knowledge to grade new assignments.
Advantages of AI Grading Systems
AI grading systems offer several benefits. Firstly, they bring efficiency to the grading process. They can grade assignments much faster than human graders, making them particularly useful for large classes or online courses. Secondly, AI grading systems provide consistency. They apply the same standards to every paper, eliminating the possibility of bias or variability that can occur with human graders. Lastly, they can provide immediate feedback, allowing students to learn and improve in real-time.
Disadvantages of AI Grading Systems
Despite their advantages, AI grading systems also have limitations. They may struggle with assignments that require understanding of context, creativity, or subjective analysis. Additionally, they can make technical errors and may not always interpret student responses correctly.
Furthermore, AI grading lacks the personal touch of a human grader, which can be important for student motivation and learning.
Comparison with Human Graders
While AI grading systems can assist human graders by handling routine tasks, they are not yet capable of completely replacing human graders. Human graders are still needed to evaluate assignments that require understanding of complex ideas, creativity, and subjective judgement. In terms of accuracy, while AI grading systems can be very accurate for grading objective assignments like multiple-choice tests, their accuracy can be lower for subjective assignments like essays.

Bias in AI Grading Systems
While AI grading systems are designed to be unbiased, they can sometimes reflect the biases of their training data. If the data used to train the AI system is biased, the system itself can also be biased. It's crucial to use diverse and representative training data to mitigate this risk.
AI software market growth forecast worldwide 2019-2025
In 2020, the global AI software market is expected to grow approximately 54 percent year-on-year, reaching a forecast size of 22.6 billion U.S. dollars. AI is a term used to describe a variety of technologies referring to the creation of intelligent software or hardware able to learn and solve problems.
These include machine learning, computer vision, and Natural language processing (NLP), among others. AI is expected to have wide adoption in and implications for every industry vertical and is likely to be one of the next great technological shifts, like the advent of the computer age or the smartphone revolution.

AI Revolution: an increase or decrease in human labor?
Despite its potential to optimize the way many industries operate, AI is feared to replace human labor in some. The automotive and assembly, and telecom industries worldwide are predicted to undergo the biggest workforce cuts in the next three years due to the adoption of AI technologies.
However, infrastructure, professional services and high-tech industries are predicted to increase their workforce sizes with the adoption of AI technologies during the same time period. This highlights the somewhat polarizing effects of AI to human jobs. In some industries, the introduction of AI greatly expedites processes and minimizes human error, which leads to the replacement of human labor. While in others, AI creates new hybrid roles where humans enable machines and AI augments human capabilities.
AI’s impacts on global economic
Despite changes in the global workforce, AI is predicted to contribute to global economic growth. A 2018 global survey estimates that AI will contribute to approximately 26.1 percent of China’s GDP in 2030, 14.5 percent of the GDP in North America, and 13.6 percent of UAE’s GDP. Some of these increases in GDP stem from improvements in productivity and product enhancements due to the adoption of AI technologies.
For example, AI in the technology, media and telecommunications industry is forecast to increase global GDP in 2030 by 12.5 percent – 5.5 percent from gains associated with productivity, and 7 percent from gains associated with product enhancements.
