On Studybay, writers are ranked by clients on a 5 point scale. An average value is a decimal number and is used to form average user rating. Rating of a writer indicates an objective evaluation of their performance, and includes such factors as time the orders take, the amount of time it takes for the writer to respond to the clients, number of refunds issued for their orders, and reviews given by clients. Each writer’s rating is recalculated daily and takes the last 150 completed orders into account.

There is a number of additional factors that may increase a writer's rating.
The following factors affect a writer’s rating positively:

  • Positive reviews by clients
  • No delayed orders
  • No refunds issued for the orders
  • Confirmation of work halfway to deadline
  • High percentage of confirmations when taking new orders

A writer’s ratings and bids are the most important factors for the clients when deciding on their writer, so it’s very important for the writers to fulfill the orders on time and provide high-quality papers.

If a writer has less than 3 completed orders, they’ll have “New Writer” tag. Their rating will be calculated and will become visible only when they complete 3 orders. In order to maintain the quality of our service, new writers have following restrictions:

  • they’re unable to upload files to the orders in auction, before starting their work on an assignment
  • they can’t work on more than 4 orders at the same time

Rating formulae

A writer’s rating is calculated using the following formula:

If the result doesn’t fall into range between 1 and 5, it gets a value of 1 or 5, whichever is closer to the result.

Rating calculation for the order i (xi):

First, a base rating xi is calculated. There are two possibilities:

  1. A client rated a writer’s completed order. In this case, base rating xi equals the rating given by the client.
  2. Warranty period has expired, but the client didn’t rate a writer’s completed order. In this case, base rating xi equals 5 (by default).

Then, base rating may be modified by coefficients due to negative factors:

  • Order completed after deadline: xi=xi-0.5
  • Writer didn’t confirm working on the order halfway to deadline: xi=2 (there are two exception cases: if the writer didn’t confirm due to a valid reason, has taken the order back and carried it out; or if the writer has already uploaded the final paper and the order is completed)
  • A refund has been issued for an order:
  • A full refund (100%) to the client: xi=1
  • A split between a client and a writer: xi gets a value between 1.0 and 4.5, depending on what percentage has been refunded to a client
  • The order is 100% credited to the writer: xi=4.5

A complexity coefficient of the order i (i):

A complexity coefficient indicates the complexity of a completed order and is tied to order price. To prevent any abuse of the rating system, all orders priced less than $5 will have a complexity coefficient close to zero. The coefficient will then increase up to 0.9 for orders costing up to $40. The orders priced more than $150 are considered very complex and their complexity coefficient equals 1.5.  

Additional factors that modify order complexity:

  • A user rating set by a client has more value than the rating set automatically (see rating calculation above). If the user rating for an order has been set automatically, for this order i=i*0.7
  • If a writer has completed an order marked as “premium”, for this order i=i*2

Additional positive and negative factors (nj and pm):

Additional positive and negative factors may be applied to a calculated rating if: 

  • a writer often refuses to take new orders after bidding and being hired (more than 30%): minus 0.5;
  • a writer confirms more than 95% of orders when hired: plus 0.1;
  • refunds has been issued for more than 20% of orders completed by a writer: minus 0.4;
  • a writer has more than 20% delayed orders: minus 0.4.

Top Writers

On Top Writers page, the writers are separated by their field of specialization, based on general rating and the number of completed orders in a certain discipline or field. Each field has its separate top writers board. A writer’s position is calculated using the following formula:

A writer is positioned on the top writers board for a certain discipline if they have completed orders in that discipline or have set it as their field of specialization. Writers tagged as “new writers” can also appear on this board if they have completed orders in that disciplines. If a writer hasn’t indicated a certain discipline as their field of specialization and they have no completed orders in that discipline, this writer will not appear on the top writers board for that discipline.
