Core Technologies of Edu24 Software
The technology behind Edu24 software, from reading to output
Edu24 Engineered
Proprietary Engineering
In-house design · in-house development · built entirely in-house, no outsourcing
Every program in the 5-program lineup is built directly by Edu24's dedicated engineering team, which handles the entire process in-house — from requirements analysis to design, development, QA, deployment and after-sales support. Compared with outsourcing, this proprietary engineering system ensures faster feature updates, consistent code quality and security policies, and custom improvements optimized for each customer's environment.
OMR Automatic Recognition Engine
A high-precision mark recognition algorithm reads answer sheets automatically the moment they are scanned. It analyzes mark darkness, mark position and even traces of correction to achieve 99.9% recognition accuracy, and automatically handles exceptions such as multiple marks, blank answers and partial marks.
Excel Integration
Automatically exports grading results, score analysis and statistical data in Excel (.xlsx) format, integrating immediately with your existing academic workflow.
Built-in SQLite DB
Runs on local files without installing a separate DB server. Exam history, student data and grading results are stored safely, and backup and restore are simple.
Installed · transferable to another PC
Install it in a few steps with the installer — and when needed, move it to another PC and keep grading in the same environment.
Real-time Statistical Analysis
Calculates per-question correct rates, discrimination and difficulty in real time, and automatically generates all the statistics education requires — score distributions, rankings, standard deviations and more.
License Key Activation System
Software activation is based on a unique license key. After activation the program can be used without limit on that PC, and keys are reissued when you replace your PC. It works normally even offline, with no network connection.

Why Edu24 software
OMR software developed in-house by Edu24, from scanning to output
Edu24 develops every part of its software in-house, from scanner reading to grading and output. It comes in five editions for the different testing practices of schools, universities, academies and organizations, each with the features that setting needs.
5Editions by purpose
3Output formats (NEIS CSV · Excel · PDF)
0No server needed — runs on a PC
TWAINDirect scanner control · simplex · duplex
PYTHON READING ENGINE
Built in Python, the language of choice for image recognition
OMR software has long been written in C and C++. Edu24 built a new reading engine in Python — the language favored in image recognition and AI — with the OpenCV and NumPy image-processing libraries, handling sheet alignment and mark recognition through image processing.

Six reasons we recommend it
01
In-house Python reading engine
Corrects sheet position using timing marks, with darkness, area and noise sensitivity adjustable to each sheet.
02
Works with your scanner as is
Controls the scanner directly via TWAIN using the manufacturer driver settings, for both simplex and duplex scanning.
03
Results ready for NEIS
Exports results as a CSV file ready to upload to NEIS, Korea’s national school information system — no manual re-entry needed.
04
One PC, no server
Each test session is stored on the PC as an SQLite file — no server needed, and copying the session folder is a full backup.
05
Excel and PDF reports
Exports results to Excel (.xlsx) and creates an individual score report PDF for each student.
06
Automatic updates
The program checks for new versions and installs them automatically, so it is always up to date. (Except Edu24 School)
For: middle and high schools across Korea — regular exams (midterms and finals)
An OMR grading program specialized for middle and high school regular exams. It automatically reads 4- and 5-choice multiple-choice answers and outputs results in the format required for NEIS grade processing. It supports every function needed for regular exams, including batch grading by subject and class, multiple correct answers and weighted scoring.
