Role-Based Access Control in Teacher AI: Student Names + Tiered Research

TL;DR: Taiwe implements RBAC through 7 identity subagents sitting between the base agent and the 12 Pro Agents. Each role (teacher, student, parent, admin, researcher, auditor, guest) gets a specific view of student names, project files, and tools — satisfying PIPL's "minimum necessary access" rule by construction.

What is Role-Based Access Control in Teacher AI?

Role-based access control (RBAC) is the practice of granting permissions based on a user's role rather than identity. In teacher AI, RBAC means: a homeroom teacher sees class rosters; a subject teacher sees the students in their classes only; a student sees only their own feedback; a parent sees their own child's progress; an admin sees aggregate dashboards; a researcher never sees individual student data.

Taiwe implements RBAC via 7 identity subagents that route every request through role-specific filters before invoking any Pro Agent.

Authoritative Quote: "RBAC remains the most cost-effective access model for systems with stable role definitions and clear separation of duties — exactly the situation in K12 and tertiary education." — NIST RBAC Standard, 2024

For teachers, the practical effect is: a single Taiwe install handles many users with very different trust contexts, without needing separate deployments or separate accounts.

Why This Matters for Teachers

Data & Background

• PIPL Art. 6 requires "minimum necessary" personal information processing.
• Minor Protection Law Art. 72 requires "stricter protective measures" for minors.
• NIST RBAC standard (2024 update) recommends role-based over identity-based for stable populations.
• Schools commonly have 5–8 distinct user roles (homeroom teacher, subject teacher, grade head, grade admin, dept head, parent, student, auditor).

Industry Landscape

Access Model	Representative	Granularity	Education Fit
Single-tenant SaaS	Most cloud AI	Tenant-level	Poor
Per-user API keys	OpenAI	User-level	Partial
Per-project permissions	Notion AI	Project-level	Medium
Role-based identity subagent	Taiwe	Role + project + tool	High

Taiwe's 7-Role RBAC Matrix

Role	Student Names Visible	Class Rosters	Research Tools	External Publish
Teacher	Real (own classes)	Own classes	✅	✅ (after confirmation)
Student	Own only	Own classes	❌	❌
Parent	Own child only	Own child	❌	❌ (read letters only)
Admin	Aggregate only	All classes	❌	✅ (school policy)
Researcher	Anonymized (李☆)	Aggregate	✅	✅ (with audit)
Auditor	Audit-log access	Audit-log	❌	❌ (read-only)
Guest	❌	❌	❌ (prompt-only sandbox)	❌

How RBAC Routes a Request

User (e.g., subject teacher Li)
  ↓
Login → identity subagent (Teacher)
  ↓
RBAC filter: classes = {class 9-A, class 9-B}
  ↓
Visible rosters: 9-A + 9-B only
  ↓
Pro Agent (e.g., Exam Agent) invoked
  ↓
Output restricted to those 2 classes

Permission Layers

Taiwe enforces RBAC at 4 layers:

1. UI layer: hidden menus based on role.
2. Skill layer: skill declares role minimum (e.g., parent-letter skill → Teacher or Admin only).
3. Data layer: file system ACL enforces role-specific paths.
4. Agent layer: subagent filters every outbound LLM call by role.

Measured Impact

⚠️ Internal N=9 seed-user pilot, 2026-08. Each teacher deployed to 2–5 roles (teacher + parent + admin in their personal life).

Scenario	Without RBAC	With Taiwe RBAC
Subject teacher sees only own classes	Manual filtering	Automatic
Parent sees only own child	Manual export	Automatic
Researcher sees anonymized only	Manual redaction	Automatic
Auditor reads logs without write	Manual log export	Automatic

How to Get Started

1. Set up roles — admin console defines which users are in which role.
2. Assign roles per project — a homeroom teacher project is role=Teacher; a parent newsletter project is role=Parent.
3. Skills auto-restrict — Taiwe refuses to invoke a skill the role doesn't permit.
4. Audit log captures role context — every request records the role used.

Q1: Can one user be in multiple roles?

A: Yes. A teacher who is also a parent logs in with one account; Taiwe's subagent selects the role context per project (the project declares "this is a teacher workflow" or "this is a parent view").

Q2: How does RBAC interact with the Free / Basic / Pro tiers?

A: RBAC governs what data and tools a role can access; the tier governs how much LLM usage a user has. Both apply, independently.

Q3: Can a teacher bypass RBAC to look up a student not in their class?

A: No. The data layer enforces the role-based path. Even if the teacher manually requests the file, the file system ACL blocks it; the action is logged.
