An international business ranking has placed Beijing-based Walnut Coding among the top 50 education technology providers globally. While the company's financial success highlights the commercial demand for computer science programs, parents and educators must look past market valuations to evaluate classroom quality. Understanding how kids learn to program and how to assess software safety can help families choose the right educational tools.
What Happened
In August 2026, TIME and market research firm Statista released their list of the World's Top EdTech Companies, which ranked Walnut Coding at No. 44 globally. Out of the 500 recognized companies, Walnut Coding was the only China-based computer science platform for young learners to make the top 100. However, the ranking's methodology heavily favors business metrics. According to TIME's official criteria, financial indicators like funding, revenue, and market capitalization account for 70 percent of a company's total score. The remaining 30 percent evaluates "industry impact," including website traffic and intellectual property.
As we have seen with shifts in China's digital learning sector, corporate expansion does not always correlate with positive learning environments. Founded in 2017, Walnut Coding sells curriculum, hardware, and NUTS, its proprietary block-based visual coding platform. The company also announced a 2025 collaboration with international bodies to support global youth digital literacy.
The Bigger Picture
For educators, a company's balance sheet tells us very little about how well a child will learn. To measure true classroom value, researchers suggest moving away from financial metrics. A study published in Smart Learning Environments recommends using the "EdTech Viability Index" alongside the "5Es framework." This framework analyzes efficacy, effectiveness, ethics, equity, and environmental impact. These benchmarks assess whether a tool actually improves student comprehension and if it is practical to implement.
When evaluating tools that incorporate artificial intelligence, a framework published in Technology, Knowledge and Learning urges school systems to assess tools across four dimensions: clarity, feasibility, pedagogical value, and learner focus.
When learning to program, many platforms rely on block-based visual coding. According to the Educational App Store, block coding is real programming that teaches key algorithmic concepts like sequencing, loops, and variables without the frustration of syntax errors. Yet, choosing between proprietary platforms like Walnut Coding or open-source standards like MIT's Scratch involves major trade-offs. Open platforms offer massive, collaborative global communities that motivate children. However, as noted by Robotical, these same public forums present safety and safeguarding concerns. Some school districts even ban them in favor of account-free, closed alternatives.
What This Means for Families
When a platform is proprietary and paid, parents often receive structured lesson plans and progress dashboards in a safer, closed online ecosystem. These features come with a price tag, whereas tools like Scratch and Code.org are entirely free.
Claims about official partnerships also require scrutiny. While corporate announcements claim ties with organizations like UNESCO to build digital skills, UNESCO's actual curriculum frameworks, such as the Media and Information Literacy resources, prioritize public, open-source toolkits over private, commercial software. UNESCO’s guidelines emphasize human agency and ethical AI evaluation rather than recommending specific consumer products. Only 16 percent of countries explicitly guarantee educational data privacy by law, making it necessary for parents to check the privacy policy of any tool, whether proprietary or open.
This echoes our previous reporting on youth digital safety and the growing need for offline educational alternatives that secure student data.
What You Can Do
- Focus on pedagogical design rather than corporate rankings when choosing software, checking whether the tool challenges your child to use higher-order logical thinking.
- Evaluate privacy policies before creating student accounts, choosing closed or account-free apps if you want to avoid open online forums.
- Use free, open-source resources like Scratch or UNESCO's "Growing up in a Connected World" guide to build foundational digital skills without paying for proprietary subscriptions.
