Use Case: Professional Certification (Verifiable OB 3.0)

Types of certification Studeia supports

Open Badges 3.0 — verifiable credentials

Each UserBadge in Studeia generates:

1. Public verification page

/badges/verify/[userBadgeId] (no authentication required):

+----------------------------------------------------+
|  🛡️ Verified Credential — OB 3.0                 |
+----------------------------------------------------+
|  [Issuer logo] XYZ Academy                         |
|                                                    |
|       🏆 ENEM 2026 Champion                        |
|       Top 10% on official practice exam            |
|                                                    |
|  Awarded to: MARIA SILVA                           |

|  [Download JSON-LD]  [Verify online]               |
+----------------------------------------------------+

2. JSON-LD compatible with Open Badges 3.0 (W3C VC model)

/api/badges/verify/[userBadgeId] (authenticity is established by resolving this public URL/API against the platform's registry; the cryptographic proof field below is on the roadmap and not yet embedded):

{
  "@context": [
    "https://www.w3.org/2018/credentials/v1",
    "https://purl.imsglobal.org/spec/ob/v3p0/context.json"
  ],
  "type": ["VerifiableCredential", "OpenBadgeCredential"],
  "issuer": {
    "id": "https://xyz-academy.com",
    "type": "Profile",
    "name": "XYZ Academy"
  },
  "issuanceDate": "2026-05-24T10:00:00Z",
  "credentialSubject": {
    "id": "did:web:user:maria-silva",
    "type": "AchievementSubject",
    "achievement": {
      "id": "https://xyz-academy.com/badges/enem-champion-2026",
      "type": "Achievement",
      "name": "ENEM 2026 Champion",
      "description": "Top 10% on official practice exam",
      "criteria": { "narrative": "Top 10% on practice exam X" }
    }
  },
  "proof": { ... cryptographic signature — on the roadmap, not yet issued ... }
}

3. Schema.org EducationalOccupationalCredential

So Google + LinkedIn can discover it:

{
  "@type": "EducationalOccupationalCredential",
  "name": "ENEM 2026 Champion",
  "description": "Top 10% on official practice exam",
  "credentialCategory": "achievement",
  "dateCreated": "2026-05-24",
  "url": "https://xyz-academy.com/badges/verify/abc",
  "recognizedBy": {
    "@type": "Organization",
    "name": "XYZ Academy"
  },
  "about": { "@type": "Person", "name": "Maria Silva" }
}

4. LinkedIn sharing

Today, the credential holder shares the public verification URL on LinkedIn manually. A one-click native "Add to Profile" button is on the roadmap.

Quiz engine for certification exams

Typical configuration

{
  "configuration": {
    "maxAttempts": 1,
    "timeLimitMinutes": 180,
    "shuffleQuestions": true,
    "shuffleOptions": true,
    "accessCode": "CERT2026",
    "scoringPolicy": "latest",
    "reviewMode": "after_due_date",
    "passingScore": 70,
    "showResultsToStudent": false,
    "allowGoBack": false
  },
  "questions": [...]  // 100+ questions from the question bank
}

Lockdown + passive integrity

Enable requireLockdownBrowser (Safe Exam Browser or the StudeiaMobile app), ipWhitelist, and accessCode. QuizAttempt persists in the background:

• tabSwitchCount: left the tab during the exam
• copyPasteCount: copy/paste/cut attempts
• blurCount: window blur events
• timeSpentSec: total time (average time per question is derived as this ÷ number of questions)
• ipAddress, userAgent
• flagged / flagReason: true when any signal exceeds the threshold

Inline in the administrator's gradebook:

Student name  | Score | Flags
Maria Silva   | 87    | 🛡️ Tab switches: 12 (suspicious)
John Smith    | 76    | (no flags)

Admin decides the action: invalidate, keep, or require an in-person retake.

Psychometric analytics

After the exam, /quiz-analytics returns:

• Item difficulty (% who answered each question correctly)
• Point-biserial discrimination (questions that do NOT differentiate strong from weak learners = candidates for removal)
• Distractor analysis (which wrong answer option is most popular)
• Cronbach's alpha (internal consistency >= 0.7 = reliable test)
• Score distribution

For certification use: identifies problematic questions + validates test reliability.

Active proctoring (limitation)

For certifications that require webcam/microphone/screen-sharing proctoring (AWS, Cisco, CFA, etc.):

Studeia does NOT have this natively (privacy + data protection concerns).

Solutions:

1. Integrate with Examity / ProctorU / Honorlock via LTI 1.3 — learner takes the exam in the Studeia window, proctoring handled by the external service
2. For in-person exams (authorized testing center): traditional physical proctoring + Studeia as the exam delivery system

Public API for integrations

Professional licensing boards consult certifications via API:

# Badge catalog (scope gamification:read)
GET https://[institution].studeia.com/api/institution/gamification/badges
Authorization: Bearer mia_...

# Validate a specific issued credential (public, no auth required)
GET https://[institution].studeia.com/api/badges/verify/[userBadgeId]

The board processes the result via ETL into its own system.

For deeper integration: webhook automation in Studeia notifies the board when a learner completes a compliance course:

Trigger: lesson_completed (tagged "certification-exam")
Action: send_webhook → POST https://board.gov/api/certifications
  Body: { studentId, certificationName, completedAt, score, badgeVerificationUrl }

Learner billing (limitation)

Studeia is NOT a course-selling platform — there is no native checkout, learner billing, or affiliate system.

To sell courses/certificates (checkout, affiliates, marketplace in the style of Hotmart/EadBox):

Solution: use EadBox or Hotmart as the front end (checkout + affiliates) + Studeia as the LMS via API. Learner pays on EadBox/Hotmart → webhook automatically creates enrollment in Studeia.

TCO for 1,000 certifications/year

Studeia is typically 40–50% cheaper + setup in 2 months vs. 6–12 months for a custom build.

From plan to practice

The complete workflow — course, lockdown exam, verifiable badge — can be assembled and tested in the free demo account before signing any contract. Issue a test badge and open the public verification page: it's the fastest argument for convincing the licensing board or HR department that will consume your certifications. Details on the professional certification page.

Transparency note: TCO figures are illustrative estimates — not quotes.
