As a university entrance exam preparatory school, Sundai Preparatory School provides support tailored to each student’s target university and academic level, primarily operating high school student classes and high school graduate classes.

As part of the public relations initiatives for the high school student classes, the school planned to refresh its enrollment guide materials distributed to high school students. This initiative was driven by a desire to address student needs appropriately by listening to their raw feedback, and to improve brand awareness in specific regions where it faced challenges. Consequently, the research was conducted with the objective of understanding market needs and the level of brand recognition among high school students across different regions.

To conduct a competitive analysis aimed at differentiating the school from its competitors, Skyfall—leveraging its core strength in researcher-driven analysis—supported the research project.

Research Objectives

・Gathering information to support the renewal of enrollment guide brochures

・Understanding high school students’ needs to formulate initiatives for competitive differentiation

Challenges Before the Research

・Understanding high school students’ needs aimed at a renewal of the enrollment guide brochure

・Improving awareness of the school’s environment and initiatives tailored to match high school students’ needs

Outcomes Achieved Through the Research

During the reporting session to share the analytical results, the client highly valued the researcher’s flexibility in handling additional requests and proposing concrete actions for the brochure refresh from a completely different angle than previous studies conducted by other companies.

In the competitive analysis specifically, while the general response trends matched initial assumptions, breaking down and examining the data closely by region and segment led to new insights and provided backing for internal hypotheses. Furthermore, the gap between high school students’ needs from a preparatory school and Sundai Preparatory School’s actual strengths became clear, providing valuable insights to guide future promotional strategies.
