How AssessPrep is turning test scores into data schools can use

A test score tells a school how a student performed, but not necessarily where their understanding is strong or weak. AssessPrep, an assessment platform, tags every question to a topic and curriculum standard, allowing schools to see where an individual student or an entire class is falling short.

The platform, headquartered in Gurugram with operations in Jaipur, helps schools create, deliver, grade, and analyse tests, primarily for international curricula such as IB, Cambridge IGCSE, and Advanced Placement. It works with more than 800 schools, with an AI-first approach designed to save teachers time while giving schools more detailed data on student learning.

Co-founder Karan Gupta traces the idea back to something he noticed through college and in the years that followed. Governments around the world were increasing spending on education, but student outcomes in reading and mathematics weren’t improving at the same pace.

His conclusion was that assessment, rather than teaching, was the weak link. Schools weren’t able to accurately measure what students were and weren't learning.

That became the premise behind AssessPrep.

Gupta studied economics at Shri Ram College of Commerce (SRCC) and did a master's degree in economics at Jawaharlal Nehru University (JNU). He co-founded the company in 2013 with two college friends, Shikhar Sethi and Abhimanyu Jhajharia, both computer science graduates from BITS Pilani’s Dubai Campus. The trio initially worked on a different product before launching AssessPrep in 2016.

Making assessments more efficient

Gupta describes AssessPrep as covering five stages of the assessment cycle: creating a test, delivering it, monitoring students while they take it, grading it, and analysing the results.

Test creation starts with the curriculum. A teacher selects a subject and question type, and the AI generates questions aligned with that curriculum's framework. Teachers can also choose from a bank of nearly 70,000 exam-style questions or upload an old paper test as a PDF and convert it into a digital test.

The platform can lock the screen so students cannot open other tabs or applications while taking a test, a feature schools use to prevent cheating. Schools that aren’t ready to move fully to digital assessments can also deliver the same test on paper.

The interface supports 13 languages, which is useful given the number of countries where AssessPrep operates.

Monitoring begins once students are taking the test. Teachers can assign accommodations such as extra time, a spellchecker, text-to-speech or a calculator through a toggle, rather than handling the paperwork traditionally associated with them.

Grading is where Gupta sees a more difficult problem. Multiple-choice questions can be automatically graded, but essays require a closer look, more like human judgement.

AssessPrep's AI grades written answers against criteria set by the teacher, such as vocabulary or argument structure. Gupta puts the current accuracy at 85% to 90%.

Teachers can also provide the AI with a few essays they have already graded to align its marking more closely with their approach. Every AI-graded answer is then sent to a teacher for review before it reaches the student.

Paper tests go through a similar process. A teacher photographs the answer sheets, and the platform matches each page to the right student before grading it.

The analysis stage is where AssessPrep attempts to answer questions that an overall percentage cannot. Every question is tagged to one of more than 600 built-in curriculum standard sets, including IB, Cambridge, NGSS, Advanced Placement, and ACARA, allowing results to be broken down by topic rather than showing only an overall score.

”A score doesn't tell a teacher what a student does or doesn't know," Gupta says. “Tagged data does.”

The technology and its guardrails

AssessPrep integrates with tools schools already use, including Google, Microsoft, Canvas, and ManageBac. The platform runs on Ruby on Rails and React, and is hosted on Google Cloud across regions to meet local data rules.

It uses several AI models, including those from OpenAI, Google and Anthropic. AssessPrep runs its own evaluations to determine which model works best for a particular task and can switch models as better ones become available.

Working with student data across more than 85 countries also makes privacy a core part of the platform. AssessPrep says it is GDPR-compliant and meets the EU AI Act. No name, gender or race is shared with the AI during grading, and the models are not trained on any school’s data.

The platform also keeps teachers in the loop. Every AI-graded answer and AI-generated assessment is reviewed by a teacher before it reaches a student.

“Our platform is an assistant for the teacher to make their processes more efficient,” Gupta says. “You review whatever the AI has done before you publish it.”

Schools can decide how much control to give the AI. Some use it only to draft feedback, with teachers assigning marks themselves. Others allow the AI to handle both, provided a teacher signs off before the results are released.

The business behind it

AssessPrep operates in the digital assessment and e-learning software segment of the K-12 edtech sector, valued at $13.85 billion in 2024 and projected to reach $32.04 billion by 2033, growing at a CAGR of 9.9%, according to Grand View Research. Its competitors include Exam.net, Canvas LMS, and Otus.

The platform sells an annual, per-student subscription, ranging from $6 per student for large US districts to $24-25 for small schools, depending on the plan.

It currently works with more than 800 schools across over 85 countries. Most are private international schools serving Grades 6-12, plus a growing base of US public districts and budget schools in Africa.

AssessPrep claims to have reclaimed more than 1 million hours of teacher time. In a 2025 AssessPrep survey of 93 international schools, 78% of teachers said AI grading saved them over 30 minutes per assessment, and 73% said tools like anonymous grading and automated scoring improved efficiency.

"AssessPrep is helping us use AI in a meaningful, responsible, and relevant way," says Shefalika Kumar Chitkara, of Singapore International School, Mumbai.

At American International School of Guangzhou, Audrey Boettcher calls the platform's lockdown mode "the game changer for me this year".

Bootstrapped and staying that way

AssessPrep has not raised external funding. Its growth has been funded entirely through the founders' own capital, which has been reinvested into the business. The founders say the company is now profitable and does not need to raise funds.

Revenue has grown by roughly 60% year on year over the past four years, and the company expects this year's revenue to be in the $2 million to $2.5 million range. The company has a team of about 50 people across Gurugram and Jaipur.

“We have enough in the bank to avoid the growth pressure that comes with investors,” Gupta says.

In the near term, AssessPrep plans to grow within its existing British and American curriculum markets while expanding into Indian national-curriculum schools as CBSE moves toward digitisation.

Longer term, Gupta wants to take what AssessPrep has learned across international curricula more broadly and make digital assessment affordable for schools across budgets. The company has no plans to expand into universities or hiring assessment platforms.
