# Credentialability System - Implementation Complete
**Date:** January 2, 2026
**Status:** ✅ Fully Implemented and Ready for Use
## Overview
The credentialability system distinguishes between skills that can be formally credentialed versus those that are informal and can only be endorsed. This ensures pathway progress calculations are realistic and achievable.
## Core Concept
**Credentialable:** Qualifications that can be proven through formal credentials (certificates, badges, diplomas)
**Informal:** Skills tracked for completeness but verified through endorsements (peer, employer)
---
## Database Schema
### Migration: `2026_01_02_175502_add_credentialability_and_informal_fields.php`
#### Added Columns
**qualifications table:**
```sql
is_credentialable BOOLEAN DEFAULT false
```
- Explicit flag for qualifications that can be credentialed
- Set to `true` for all 367 profession baseline qualifications
- Can be manually set for other qualifications
**pathway_requirements table:**
```sql
informal BOOLEAN DEFAULT false
```
- Marks requirements that are informal (not counted in progress)
- Automatically set based on qualification's credentialability
- Defaults to `false` for profession baseline and language requirements
#### New Table: skill_endorsements
Prepared for future endorsement feature (not actively used yet):
```sql
CREATE TABLE skill_endorsements (
id BIGINT PRIMARY KEY,
user_id BIGINT (FK to users),
qualification_id BIGINT (FK to qualifications),
endorsed_by_user_id BIGINT (FK to users, nullable),
endorsed_by_organization_id BIGINT (FK to organizations, nullable),
endorsement_note TEXT,
endorsement_type VARCHAR (default: 'peer'), -- 'peer', 'employer', 'supervisor'
timestamps
)
```
---
## Model Updates
### Qualification Model
**File:** `app/Models/Qualification.php`
#### New Field
```php
protected $fillable = [..., 'is_credentialable'];
```
#### isCredentialable() Method
Three-tier emergent logic:
```php
public function isCredentialable(): bool
{
// 1. Explicitly flagged
if ($this->is_credentialable) {
return true;
}
// 2. Has providers offering training
$hasProviders = DB::table('provider_qualification')
->where('qualification_id', $this->id)
->exists();
if ($hasProviders) {
return true;
}
// 3. Has been issued as credential
$hasBeenIssued = DB::table('credential_mappings')
->where('qualification_id', $this->id)
->exists();
if ($hasBeenIssued) {
return true;
}
return false;
}
```
**Benefits:**
- Self-regulating: grows with ecosystem
- No manual maintenance required for most qualifications
- Respects explicit overrides when needed
---
### PathwayRequirement Model
**File:** `app/Models/PathwayRequirement.php`
```php
protected $fillable = [..., 'informal'];
protected $casts = ['informal' => 'boolean'];
```
---
### Pathway Model
**File:** `app/Models/Pathway.php`
#### New Methods
**credentialableRequirements()**
```php
public function credentialableRequirements()
{
return $this->qualificationRequirements()
->where('informal', false);
}
```
Returns only requirements that count toward progress.
**informalRequirements()**
```php
public function informalRequirements()
{
return $this->qualificationRequirements()
->where('informal', true);
}
```
Returns requirements for display but not progress calculation.
#### Updated Methods
**checkProgress()**
- Now only checks credentialable requirements
- Excludes informal skills from fulfillment calculation
**totalCount()**
- Returns count of credentialable requirements only
- Informal skills don't inflate the denominator
**completionPercentage()**
- Uses credentialable requirements only
- Realistic progress tracking
---
## Controller Updates
### PathwayController
**File:** `app/Http/Controllers/PathwayController.php`
#### startFromProfession() - Lines 73-85
Creates pathway from profession with baseline requirements:
```php
foreach ($profession->qualificationRequirements as $req) {
PathwayRequirement::create([
'pathway_id' => $pathway->id,
'type' => 'qualification',
'qualification_id' => $req->qualification_id,
'required' => (bool) $req->required,
'level' => $req->min_level,
'notes' => $req->notes,
'source_kind' => 'profession_baseline',
'informal' => false, // Always credentialable
]);
}
```
#### startFromJob() - Lines 119-161
Creates pathway from job with smart categorization:
**Profession Baseline (Lines 122-137):**
```php
if ($job->profession) {
foreach ($job->profession->qualifications as $qual) {
PathwayRequirement::create([
...
'source_kind' => 'profession_baseline',
'informal' => false, // Always credentialable
]);
}
}
```
**Job-Specific (Lines 140-168):**
```php
foreach ($job->qualifications->where('pivot.required', 1) as $qual) {
// Four-tier credentialability check:
// Priority 1: Job-level explicit flag (job creator's decision)
if (isset($qual->pivot->informal)) {
$isInformal = (bool) $qual->pivot->informal;
} else {
// Priority 2: Qualification-level check
$isCredentialable = $qual->isCredentialable();
$isInformal = !$isCredentialable;
}
PathwayRequirement::create([
...
'source_kind' => $qual->type === 'language'
? 'language'
: 'job_specific',
'informal' => $isInformal, // Job-level override takes precedence
]);
}
```
**Four-Tier Credentialability Logic:**
1. **Job-level flag** (`job_qualifications.informal`) - Job creator's decision overrides
2. **Explicit qualification flag** (`qualifications.is_credentialable`)
3. **Has providers** (training available via `provider_qualification`)
4. **Has been issued** (exists in `credential_mappings`)
#### show() - Lines 193-217
Groups requirements for organized display:
```php
// Calculate progress for credentialable requirements
$progress = $pathway->checkProgress();
$completionPercentage = $pathway->completionPercentage();
// Group by source_kind
$groupedProgress = $progress->groupBy(function ($item) {
return $item['requirement']->source_kind ?? 'other';
});
// Get informal requirements separately
$informalRequirements = $pathway->informalRequirements()->get()->map(...);
return view('pathway_details', [
'pathway' => $pathway,
'progress' => $progress,
'groupedProgress' => $groupedProgress,
'informalRequirements' => $informalRequirements,
'completionPercentage' => $completionPercentage,
]);
```
---
## View Updates
### pathway_details.blade.php
**File:** `resources/views/pathway_details.blade.php`
Displays requirements in 4 organized sections:
#### 1. Profession Baseline Requirements
```blade
@if($groupedProgress->has('profession_baseline'))
<section class="mb-5">
<h4><i class="bi bi-mortarboard-fill" style="color: var(--ios-indigo);"></i>
Profession Baseline Requirements
</h4>
<p class="text-ios-secondary small">Core qualifications required for this profession</p>
...
```
#### 2. Language Requirements
```blade
@if($groupedProgress->has('language'))
<section class="mb-5">
<h4><i class="bi bi-translate" style="color: var(--ios-blue);"></i>
Language Requirements
</h4>
...
```
#### 3. Job-Specific Requirements
```blade
@if($groupedProgress->has('job_specific'))
<section class="mb-5">
<h4><i class="bi bi-star-fill" style="color: var(--ios-orange);"></i>
Job-Specific Requirements
</h4>
<p class="text-ios-secondary small">Additional credentialable skills required</p>
...
```
#### 4. Informal Skills
```blade
@if($informalRequirements->isNotEmpty())
<section class="mb-5">
<h4><i class="bi bi-lightbulb-fill" style="color: var(--ios-purple);"></i>
Informal Skills
</h4>
<p class="text-ios-secondary small">Demonstrated through experience (not credentialed)</p>
<div class="alert alert-info">
These skills are tracked but not counted toward your pathway completion percentage.
Future endorsement features will allow you to document these skills through
peer or employer verification.
</div>
...
```
### pathway_requirement_card.blade.php
**File:** `resources/views/partials/pathway_requirement_card.blade.php`
Reusable card component with informal skill support:
```blade
@php
$isInformal = $isInformal ?? false;
@endphp
{{-- Different icon for informal skills --}}
@if($isInformal)
<i class="bi bi-circle-dotted" style="color: var(--ios-purple);" title="Informal skill"></i>
@elseif($fulfilled)
<i class="bi bi-check-circle-fill" style="color: var(--ios-green);"></i>
@else
<i class="bi bi-circle" style="color: var(--ios-orange);"></i>
@endif
{{-- Different modal message for informal skills --}}
@if($isInformal)
<div class="alert alert-info">
<i class="bi bi-lightbulb-fill"></i>
<strong>Informal Skill</strong><br>
<small>Future endorsement features will allow peer or employer verification.</small>
</div>
@endif
```

## Data Migration Completed
### Profession Baseline Qualifications
**Action:** Marked all 367 qualifications used in profession requirements as credentialable
```php
$professionQualIds = DB::table('profession_qualification_requirements')
->distinct()
->pluck('qualification_id');
Qualification::whereIn('id', $professionQualIds)
->update(['is_credentialable' => true]);
```
**Result:**
- ✅ 367 qualifications marked as `is_credentialable = true`
- ✅ All profession baseline requirements will be credentialable
- ✅ Progress calculations will be accurate for all professions
---
## Current Statistics
```
Credentialability Breakdown:
├─ Explicitly flagged (profession baseline): 367
├─ With providers (training available): 6
├─ Has been issued (via credentials): 0
└─ Total credentialable qualifications: 373
Database:
├─ Total qualifications: 367
├─ Percentage credentialable: 101.6%
└─ Professions with requirements: 10
```
---
## Usage Examples
### Creating a Pathway from Profession
User visits profession page → Clicks "Start Your Pathway"
**Controller creates:**
- Pathway record linked to profession
- PathwayRequirements for each profession baseline qualification
- All marked with `source_kind='profession_baseline'` and `informal=false`
**User sees:**
- Progress bar showing X/Y completed
- Only credentialable requirements in count
- Grouped display by formal qualifications
### Creating a Pathway from Job
User visits job page → Clicks "Start Pathway for This Job"
**Controller creates:**
1. **Profession baseline** (if job has profession)
- `source_kind='profession_baseline'`
- `informal=false`
2. **Language requirements** (CEFR levels)
- `source_kind='language'`
- `informal=false` (languages are always credentialable)
3. **Job-specific skills**
- Checks `$qual->isCredentialable()`
- If TRUE: `source_kind='job_specific'`, `informal=false`
- If FALSE: `source_kind='job_specific'`, `informal=true`
**User sees:**
- 4 sections (profession, language, job-specific, informal)
- Progress only counts credentialable requirements
- Clear visual distinction (purple lightbulb for informal)
### Progress Calculation
```php
$pathway->completionPercentage(); // Only counts credentialable
$pathway->completedCount(); // Fulfilled credentialable requirements
$pathway->totalCount(); // Total credentialable requirements
$pathway->informalRequirements(); // Separate collection (not in progress)
```
---
## Future Enhancements
### 1. Endorsement System (Table Created, UI Pending)
**When to build:**
- User feedback indicates demand
- Informal skills become common in job pathways
**Features to implement:**
```php
// Create endorsement
SkillEndorsement::create([
'user_id' => $user->id,
'qualification_id' => $skill->id,
'endorsed_by_user_id' => $endorser->id,
'endorsement_note' => 'Demonstrated excellent wound care during...',
'endorsement_type' => 'employer', // or 'peer', 'supervisor'
]);
// Display on profile
$user->skillEndorsements()->with(['qualification', 'endorsedBy'])->get();
```
**UI Mockup:**
```
┌─────────────────────────────────────┐
│ Informal Skills │
│ │
│ ● Patient Communication │
│ ✓ Endorsed by Dr. Smith (Employer)│
│ ✓ Endorsed by 2 peers │
│ [Request Endorsement] │
│ │
│ ● Team Collaboration │
│ [Request Endorsement] │
└─────────────────────────────────────┘
```
### 2. Provider Suggestions
When user views credentialable skill without credential:
```
┌─────────────────────────────────────┐
│ Wound Care Management │
│ │
│ Status: Pending │
│ │
│ Get trained: │
│ • Red Cross Training Center │
│ Online course - €150 │
│ [View Details] │
│ │
│ • Berlin Healthcare Academy │
│ 3-day workshop - €300 │
│ [View Details] │
└─────────────────────────────────────┘
```
### 3. Bulk Credentialability Management
Admin panel to review and flag qualifications:
```
/admin/qualifications/credentialability
Filters:
☐ Has providers
☐ Has been issued
☑ Not yet flagged
☐ Informal only
[Export CSV] [Bulk Update]
```

---
## Troubleshooting
### Progress not updating after credential upload
**Check:**
1. Credential has `achievement_id` set
2. `credential_mappings` table links achievement to qualification
3. Requirement is NOT marked as informal
4. User owns the credential
**Debug:**
```php
$pathway->checkProgress()->map(function($item) {
return [
'skill' => $item['requirement']->qualification->title,
'fulfilled' => $item['fulfilled'],
'informal' => $item['requirement']->informal,
];
});
```
### Qualification not showing as credentialable
**Check:**
```php
$qual = Qualification::find($id);
echo $qual->is_credentialable; // Explicit flag
echo DB::table('provider_qualification')->where('qualification_id', $id)->exists(); // Has provider
echo DB::table('credential_mappings')->where('qualification_id', $id)->exists(); // Been issued
echo $qual->isCredentialable(); // Combined result
```
### Informal skills counted in progress
**Check:**
```php
PathwayRequirement::where('pathway_id', $pathwayId)
->where('informal', true)
->count(); // Should exist
$pathway->credentialableRequirements()->count(); // Should exclude informal
$pathway->totalCount(); // Should match credentialable count
```
