The National Qualification "IT Passport" Taken by Over 300,000 People Annually

In recent years, with the acceleration of DX promotion and the evolution and utilization of AI, the importance of IT literacy education in companies has increased. Amidst this, the IT Passport exam has attracted attention as a national exam that can certify basic IT knowledge.

The IT Passport exam is a national exam conducted by the Information-technology Promotion Agency, Japan (IPA), and is a popular qualification with over 300,000 applicants annually.

Over 300,000 applicants in Reiwa 6 (2024) fiscal year

However, in learning to acquire qualifications, there are challenges such as:

・ Textbooks alone are not enough to cope with exam questions

・ Starting with past questions without basic knowledge makes it impossible to solve them

・ Learning with textbooks and then preparing for exams with past questions takes time and money

The Shortest Study Method is "Solving Past Questions"

At Shikaku-Oh, we believe that the shortest route to acquiring qualifications is "solving past questions."

However, there are challenges:

・ Don't understand the vocabulary

・ Don't understand the meaning of the questions

These challenges often lead to learning setbacks.

Therefore, Shikaku-Oh was designed and developed to provide detailed explanations, enabling users to learn while solving problems.

"Learn While Solving" Learning Experience with Detailed AI Explanations

Shikaku-Oh utilizes AI to provide detailed explanations such as:

・ Question intent

・ Basic knowledge required to solve the problem

・ Vocabulary explanations

AI provides detailed explanations to support learning

This provides a "learn while understanding" learning experience, rather than just problem practice.

Future Development

Shikaku-Oh plans to expand its services to companies and schools in the future.

・ Support for employees to acquire IT Passports

・ Learning progress management function

・ Group usage function

We are currently interviewing companies and schools about their needs and are looking for contact from companies and educational institutions considering implementation.

We look forward to hearing from people like these:

・ Companies promoting IT Passport acquisition

・ School, vocational school, and university officials

・ Companies that can support Shikaku-Oh

・ Companies considering sponsorship or advertising

・ Qualification exam operating organizations

・ Media professionals

・ Others interested in partnerships, etc.
