How the Dynasty Score works

The Dynasty Score is a 0 to 100 score for each prep center in this directory. It is built only from facts we can check on the prep center's own website or in public records. It measures how transparent a prep center is and how it operates. It is not a customer rating, it is not a recommendation, and it does not guarantee the quality of the service. Nobody can pay to change it.

When we cannot confirm a fact, it scores zero. Each profile shows how much of its score rests on facts we could verify (its coverage). A prep center with less than 60% coverage is labeled "Limited data", whatever its number.

Where the data comes from

We find prep centers through public business listings, then read each one's own website: pricing, services, turnaround, about and contact pages. Every fact that moves the score links to the page where we read it, and each profile lists those sources. We write each summary ourselves. We do not copy listings, descriptions, reviews or images from other directories. We only publish contact details a business shows on its own website.

Addresses are placed on the map with the U.S. Census Bureau geocoder. Map data © OpenStreetMap contributors, served by OpenFreeMap with OpenMapTiles.

Customer reviews are not part of the score. Each profile links to the prep center's reviews on Google so you can read them there.

Seller reviews

Sellers who used a prep center can rate it from 1 to 5 stars and describe their experience on its profile. The average and the number of reviews appear in the list, and you can sort by them. Reviews are separate from the Dynasty Score: the score measures what a prep center publishes, reviews tell you what working with it was like.

• One review per prep center for each email address. Your email is never shown.
• Write about your own experience with the service. Do not review a prep center you work for, own or compete with, and do not accept anything in exchange for a review.
• No insults, personal data, links or ads.

We publish reviews right away and do not edit them. We remove a review only if it breaks these rules, never because it is negative. Anyone can report a review, and a person checks every report. Reviews are not verified purchases, so read several before deciding.

Sponsored listings

A listing marked "Sponsored" is a paid or house placement. The label is always visible, and it changes neither the score nor the default order.

Corrections and removals

If you run a prep center and something is wrong or missing, use "Report a correction" on its profile, or add or correct a listing, with a link to the page that shows it. When an owner confirms their details, the profile says so. You can also ask us to remove a listing at info@dynastyecom.store.

Listings are checked again every 90 days. The most recent check was on Nov 13, 2026.
