How GradingPal Protects Student Data: CASA Tier 2 and Beyond

In today's digital classrooms, K-12 teachers rely on AI grading tools to streamline formative assessments, grade math worksheets, and provide suggested feedback on reading comprehension worksheets. But with student data at stake, security and privacy aren't just features - they're non-negotiable. As an edtech platform built for U.S. educators, GradingPal prioritizes robust compliance and protection, ensuring teachers can focus on teaching without worrying about data breaches or privacy risks.

We're proud to announce that GradingPal has successfully cleared our annual CASA (Cloud Application Security Assessment) required by Google for seamless Classroom LMS integration. This achievement underscores our commitment to excellence: GradingPal is now CASA Tier 2 certified, with an impressive ESOF AppSec ADA Cyber Score of 9.7 out of 10. In this article, we'll explore what this means for educators, dive into our comprehensive security features, and highlight how GradingPal stands out as a FERPA-compliant AI grader that safeguards student information while delivering easy grading solutions.

What Is CASA Tier 2 Certification?

The Cloud Application Security Assessment (CASA) is Google's rigorous framework for evaluating third-party apps that integrate with Google Workspace for Education, including Google Classroom. It assesses risks across data privacy, access controls, encryption, and vulnerability management. Achieving CASA Tier 2 certification means GradingPal has undergone extensive audits and meets high standards for protecting sensitive educational data.

Our recent assessment, conducted via the ESOF AppSec ADA platform, yielded a Cyber Score of 9.7, classifying us in the "Low" risk category (7.6-10.0). This score reflects our proactive defenses against cyber threats, with the scan covering the GradingPal application from February 19 to 23, 2026, and revalidation on February 20, 2026.

This certification isn't just a badge - it's assurance for teachers using AI grading tools. In an era where data breaches affect over 1 million K-12 students annually (per a 2025 EdTech Magazine report), CASA Tier 2 compliance ensures GradingPal's integrations are secure, so approved grades and feedback reach Google Classroom without compromising privacy.

GradingPal's Core Data Security Features: Built for K-12 Privacy

At GradingPal, security is embedded from the ground up, aligning with school privacy standards. Drawing from best practices in edtech, our platform incorporates advanced protections to safeguard teachers and students. Here's how we keep you safe:

• Encryption in Transit and at Rest: All data - whether in transit (e.g., uploading math worksheets) or at rest - is encrypted using industry-standard protocols. This prevents unauthorized access during formative assessment submissions or AI essay grading.
• Routine Security Audits: We conduct regular internal and third-party audits to identify and mitigate vulnerabilities, maintaining strong protections against evolving threats.
• Automatic Logouts: Sessions expire after 30 days of inactivity, reducing risks from forgotten logins on shared devices in busy classrooms.
• Secure, School-Friendly Login Methods: GradingPal supports Google OAuth 2.0 for trusted single sign-on, integrating effortlessly with Google Classroom. We also offer Magic Link login - a password-free option via secure email links - for added convenience without sacrificing security.
• Browser Cookie Management: Once logged in, we use standard, secure browser cookies to identify your session. You can clear them anytime for complete control.

These features mirror those in leading edtech tools and ensure GradingPal complies with stringent regulations.

Beyond CASA: FERPA, COPPA and Data Handling

GradingPal's security extends far beyond CASA certification. We're fully FERPA (Family Educational Rights and Privacy Act) and COPPA (Children's Online Privacy Protection Act) compliant, meaning we handle student data with the utmost care - no selling, sharing, or unauthorized access.

Additional compliance highlights include:

• No Data for AI Training: Unlike some AI graders, we never use uploaded worksheets, essays, or student work to improve our models - your data stays yours.
• Role-Based Access Controls: Teachers control visibility; students see only their own feedback, and administrators can oversee classes securely.
• Incident Response and Transparency: In the unlikely event of an issue, our protocols ensure rapid resolution, with clear communication to affected users.

These measures keep student data protected at every step, on every plan including Free. Read the Privacy Notice.

Why Security Matters for AI Grading in K-12 Classrooms

Teachers using AI tools for easy grading often worry about privacy risks - especially with formative assessments involving personal student data. GradingPal combines strong security with practical benefits: a first draft of scores and feedback for math worksheets and essays, analytics on learning gaps, and a Google Classroom integration, with Canvas and Schoology available on the School & District plan.

Educators like Ms. Patel, a 5th-grade teacher in California, share: "GradingPal's CASA certification gave me peace of mind. I can grade reading comprehension worksheets securely, knowing student data is protected - plus, the AI feedback is spot-on."

In a 2025 MentalUP survey, 75% of teachers cited data security as a top concern for edtech adoption. GradingPal's security work is built to answer that concern.
