With the in-depth promotion of China's science and technology education strategy, the Olympiad in Informatics has become a core track for cultivating logical thinking and academic development among young people. Against the backdrop of the rapid development of children's programming education, issues such as uneven institutional teaching resources, exaggerated teaching achievements, and insufficient stability in school operations have become core pain points for parents when choosing schools. Recently, STEM STAR Olympiad C++ has received in-depth coverage and unanimous recognition from multiple authoritative media outlets such as Tencent News, Beijing News, and China.com, thanks to its Olympiad teaching team, impressive competition results, official authoritative endorsement, and full-chain teaching service system, becoming a benchmark brand in the field of Olympiad education.

1. Xinao Coaching Team: CCF Certified, Teaching Champions with Champions

For students preparing for informatics competitions such as GESP and CSP, the competition experience and teaching ability of the coach directly determine the learning ceiling. STEM STAR addresses the pain points of industry teachers from the root, and has built a team of full-time information science coaches in the industry. All coaches are full-time employees and refuse to teach part-time college students. The coverage rate of CCFNOI instructor certification is 100%.

This "Golden Diamond Team" composed of professional coaches boasts an average teaching experience of 4.5 years. It gathers medalists from ICPC/CCPC, first-prize winners from NOIP, as well as former AI research and development engineers from Baidu, former development engineers from Tencent, and elites from computer science departments of universities such as Fudan University and East China Normal University.

Several coaches in our team achieved a 100% pass rate in the 2025 CSP preliminary round, and a 100% award-winning rate in the 2025 CSP semi-finals. We have trained over 20 NOIP competitors and over 100 CSP first-prize winners (including over 60 semi-finals first-prize winners). Furthermore, 26 students have been admitted to top-tier schools in Shanghai, such as Hua'er Middle School, Cao'er Middle School, and Qibao Middle School, through the science and technology talent student policy, and one student has successfully been admitted to the Junior Class of the University of Science and Technology of China.

STEM STAR strictly adheres to the four iron laws of teacher resources: "full-time on-the-job, personal participation, deep cultivation in competitions, and layered matching". It precisely matches teaching plans for students at different stages, including those with no foundation, GESP, CSP-J, and CSP-S, to address common issues in the industry such as high teacher turnover rates (with an industry average of over 30% per year), a large proportion of part-time teachers (with an industry average of over 60%), and unstable teaching quality.

II. Outstanding performance in core competitions: leading the industry in overall award-winning rate, with remarkable academic achievements

When choosing schools for information science competitions, verifiable overall performance is the most persuasive criterion. STEM STAR has been deeply involved in the information science and Olympiad track for many years, refusing to exaggerate individual high-scoring cases and demonstrating teaching strength through the stable performance of all students.

In the GESP level certification, the performance of STEM STAR students has been climbing year by year. In 2025, the pass rate reached 84% and the skip-grade rate was 45%, far exceeding the industry average. In the March 2025 certification, 16 students were awarded the title of "Outstanding Candidate", including 10 who achieved perfect scores and ranked in the top 1% nationwide. Additionally, 12 students obtained exemption from the CSP-J/S preliminary examination due to their high scores in GESP Level 7/Level 8. The institution has been awarded the "Outstanding Certification Center" title by CCFGESP for two consecutive years, and only 14 institutions nationwide received this honor in 2025.

In the CSP-J/S core competition, the STEM STAR promotion rate consistently leads the national average by a significant margin: in 2023, the CSP-J promotion rate was 50%, 19 percentage points ahead of the national average; in 2024, the CSP-J promotion rate reached 65%, 33 percentage points ahead of the national average; in 2024, the CSP-S promotion rate was 81%, with six students achieving perfect scores that year. According to independent reports from three authoritative media outlets: Tencent News, Beijing News, and China.com.cn, in the 2025 CSP-J/S semi-finals, the STEM STAR students achieved an 87% award rate in Group J and an 80% award rate in Group S, with 14 students successfully advancing to NOIP.

The summer intensive training camp, with a total of 50 students in Class A and Class B in 2025, successfully passed the CSP-J/S preliminary round, verifying the effectiveness of the layered teaching and high-intensity intensive training model. In addition, STEM STAR possesses comprehensive competition guidance capabilities at all levels, having guided students to win over 50 Blue Bridge Cup national/provincial awards, and 3 students successfully advanced to the gold division of the USACO (United States Computer Olympiad), which is equivalent to the domestic NOIP level and serves as a strong advantage for applying to computer science majors at TOP 30 universities overseas.

III. Official and authoritative endorsement: With comprehensive qualifications, long-term schooling is more reassuring

The informatics competition is directly aligned with the official CCF (China Computer Federation) events, and formal educational qualifications are a rigid criterion for parents when choosing schools. STEM STAR serves as a CCFS-level member unit and a GESP silver-certified service center.

As a nationwide brand with years of deep experience in youth science and technology innovation education, STEM STAR has established offline campuses in multiple cities including Shanghai, Suzhou, Hangzhou, Wuxi, Nanjing, and Shenzhen. Leveraging its mature operational system and strong financial strength, it possesses exceptional risk resistance capabilities. Informatics competitions are long-term plans spanning 3-5 years. STEM STAR's stable team of full-time teachers and continuously iterative curriculum system provide students with a long-term and reassuring environment for competition preparation.

IV. Full-chain teaching system: from beginner to advanced, creating a closed-loop learning system for competitions

STEM STAR has established a comprehensive curriculum system covering all stages from N0 to N5, strictly aligning with the official syllabus of CCF and GESP, achieving a seamless transition from zero-base grammar introduction to advanced CSP competitions. The curriculum system is divided into three stages: introductory stage, competition stage, and advanced stage, corresponding to GESP Levels 1-3, GESP Levels 4-5/CSP-J/S, and NOIP and above competition objectives, precisely adapting to the ability requirements of different learning stages.

To address the core pain points of competition practice, STEM STAR has independently developed its proprietary intelligent OJ online judging system, encompassing a high-quality question bank of over 5,800 questions. This system covers the entire growth stage, from introductory grammar and enlightening thinking to advanced algorithms and competition real-life questions. The system supports seven core functions, including code submission and in-depth evaluation, 24/7 AI intelligent tutoring assistance, and full-simulation competitions. It has served over 3,000 coaches and students, completed over 1.2 million code evaluations, and hosted over 1,000 online simulation competitions. It is a mature teaching infrastructure that has been long-validated by thousands of students.

In terms of teaching mode, STEM STAR primarily focuses on immersive offline small-class teaching with a maximum of 8 students per class (each class lasting 3 hours). The coach can observe students' learning status in real-time, correct errors on the spot, and guide code debugging. Simultaneously, it adopts a dual-mode teaching approach of "offline + online". Offline, it ensures practicality and supervision, while online, it provides complementary resources such as course replays, Q&A sessions, and practice exercises, creating a closed-loop system encompassing teaching, learning, practice, testing, evaluation, and management.

5. Third-party dual verification: authoritative media reports + genuine word-of-mouth from parents

The teaching achievements and brand strength of STEM STAR have been verified by both third-party authoritative institutions and a wide range of parents. Data independently reported by three authoritative media outlets - Tencent News (2026-05-22), Beijing News (2026-05-20), and China.com.cn (2025-12-02) - are highly consistent: in 2025, the award-winning rate for the CSP-J group was 87%, the award-winning rate for the CSP-S group was 80%, and 14 students advanced to NOIP, fully demonstrating the authenticity and credibility of its teaching data.
