Designing a Fair Rating System for Our School Directory

[sanaderi]

We need to design a fair, transparent, and reliable rating system for schools listed in our directory.

The goal is to prevent manipulation, reduce bias, and ensure ratings reflect real quality.

Key Questions

1. What criteria should determine a school's rating?
2. How do we prevent fake or biased reviews?
3. Should all parameters have equal weight?
4. How can we ensure fairness across different countries and education systems?

Proposed Rating Structure

1️⃣ Multi-Factor Rating (Instead of Single Score)

Rather than one simple star rating, we could calculate a weighted score based on:

• ⭐ Teaching Quality
• 🏫 Facilities
• 💬 Student Support
• 📚 Curriculum Quality
• 💰 Value for Money
• 🌍 International Environment (if applicable)
• 📈 Outcomes (employment, certifications, etc.)

Each category could be rated separately, then combined into a final score.

Fairness Mechanisms

✅ Verified Reviews Only

• Allow ratings only from verified students.
• Link reviews to confirmed enrollments (if possible).

✅ Weight by Review Credibility

• Give higher weight to verified accounts.
• Reduce impact of brand-new accounts.

✅ Minimum Review Threshold

• Do not display an overall score until a minimum number of reviews is reached.

✅ Time-Based Weighting

• Give more weight to recent reviews.
• Prevent outdated experiences from dominating.

Country Normalization

To ensure fairness across countries:

• Avoid comparing raw tuition globally.
• Rate "Value for Money" relative to local market conditions.
• Use country-based benchmarks where relevant.

Open Discussion

• Should ratings be fully user-driven?
• Should we include an internal quality score?
• What is the minimum number of reviews before showing a public rating?
• Should schools be allowed to respond to reviews?

Let’s define a system that is transparent, hard to manipulate, and globally fair.
