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.
What the WW Score measures
Every WW Score is built from four distinct quality signals, each weighted by its importance to overall homeowner satisfaction.
🛠️ Project Completion
Whether jobs were finished completely, on time, and with proper follow-through on callbacks and commitments.
💼 Professionalism
Punctuality, communication quality, attitude, appearance, and responsiveness throughout the job.
✅ Experience
Technical skill, quality of workmanship, diagnostic ability, and problem-solving capability on the job.
💰 Price Friendly
Value for money, pricing transparency, fair quotes, and absence of hidden or unexpected charges.

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