Wise Workman Platform

The WW Score &
Confidence System

How we turn thousands of homeowner reviews into a single, trustworthy quality metric — and what the confidence level behind it actually means.

Scoring System

The Wise Workman Score explained

The WW Score is a composite metric calculated across four service dimensions. It is not a simple average of star ratings — it is a confidence-adjusted, evidence-weighted score that reflects both what customers said and how much evidence exists to support each dimension.

Not a star average

We don't average star ratings. Our AI reads every review to extract explicit signals for each quality dimension separately.

Evidence-weighted

A dimension score is only assigned when there is explicit mention. Silence is not treated as a perfect score — it's treated as missing data.

Confidence-adjusted

Dimensions with few mentions are automatically discounted in proportion to their evidential weight, preventing sparse data from inflating the score.

Fake-review screened

Our AI actively screens for inauthentic patterns — repetitive language, date clustering, suspiciously uniform ratings — before any reviews enter scoring.

The Four Dimensions

What the WW Score measures

Every WW Score is built from four distinct quality signals, each weighted by its importance to overall homeowner satisfaction.

35% weight

🛠️ Project Completion

Whether jobs were finished completely, on time, and with proper follow-through on callbacks and commitments.

30% weight

💼 Professionalism

Punctuality, communication quality, attitude, appearance, and responsiveness throughout the job.

20% weight

✅ Experience

Technical skill, quality of workmanship, diagnostic ability, and problem-solving capability on the job.

15% weight

💰 Price Friendly

Value for money, pricing transparency, fair quotes, and absence of hidden or unexpected charges.

The Calculation

How the score is calculated

For each contractor, our AI engine processes the full review set through a structured pipeline before arriving at a single WW Score.

1

Review ingestion

All publicly available reviews are collected from Angi, Thumbtack, Yelp, Google, and HomeAdvisor. No reviews are modified, fabricated, or selectively excluded.

2

Authenticity screening

Our AI screens for inauthentic patterns: identical phrasing, date clustering, suspiciously uniform ratings. Flagged reviews are down-weighted or excluded before scoring begins.

3

Dimension extraction

Each review is analysed for explicit mentions of the four dimensions. Only reviews that actually discuss a dimension contribute to that dimension's score — absence of mention is recorded as no data, not a perfect score.

4

Recency & source weighting

Reviews from the past 12 months carry full weight; older reviews decay exponentially. Reviews from more tightly verified platforms carry proportionally more weight than loosely verified ones.

5

Confidence-weighted average

Dimension scores are combined into a final WW Score weighted by both their assigned dimension weight and the volume of evidence behind them. Sparse dimensions are discounted automatically.

Key principle: A WW Score of 90 based on 5 reviews is treated very differently from a WW Score of 90 based on 150 reviews. The number may look the same, but our confidence system ensures the better-evidenced contractor ranks appropriately higher in directory listings.
Score Quality

The Confidence System

Every WW Score is accompanied by a confidence level that tells you how much evidential weight sits behind the number. The same score means something very different depending on whether it is built on 4 reviews or 40.

HIGH
20+ reviews
All four dimensions are well-covered. Score is highly reliable and fully ranked.
MODERATE
8–20 reviews
Most dimensions have sufficient data. Score is reliable with minor caveats noted in the narrative.
LIMITED
3–7 reviews
Some dimensions have sparse data. Score is directionally useful — treat it as an early signal, not a verdict.
NO DATA
Fewer than 3
Insufficient reviews to calculate a reliable score. Contractor is listed but not ranked in directory results.
Confidence Level Typical Review Count What It Means for You
HIGH 20+ reviews with broad dimension coverage Score is robust. All four dimensions are well-evidenced. Treat it with full confidence.
MODERATE 8–20 reviews Score is reliable. Most dimensions covered. Minor gaps noted in the score narrative.
LIMITED 3–7 reviews Useful directional signal. Some dimensions lack sufficient mentions — read the narrative carefully.
NO DATA Fewer than 3 reviews No score is displayed. Contractor is listed but does not appear in ranked results.
How confidence is surfaced: Confidence levels are not shown as technical labels to end users. Instead, they silently influence directory rankings. A contractor with a HIGH confidence score of 80 will rank above a contractor with a LIMITED confidence score of 88 — because the evidence behind the lower score is stronger and more reliable.
Ranking Impact

How confidence affects your ranking

Here's a real-world example of how two contractors with similar scores can land in very different positions because of the evidence behind their numbers.

Transparency commitment: Every WW Score on our platform includes a "score last updated" timestamp and a detailed narrative explaining what drove the score, how many reviews were analysed, and any data quality flags identified during processing. Scores are recalculated periodically as new review data becomes available.
