Account Credits

There are a number of things to keep in mind when you have a credit.  We issue credits to expire the last day of the month of the credit, the following year. So if you got a credit on March 15, 2021, it would expire on March 31, 2022. You must call into our home office to redeem your credit.  Our number is 425-868-2304.  You are free to use that credit towards the purchase of any product, workshop or exam shown on our website. It cannot be used towards state association-sponsored programs you might see on our calendar. If you don’t purchase a product(s), apply to take an exam or register for a workshop prior to the expiration date of that credit, it will expire. It cannot be extended or re-issued. So if you have a credit, be sure to keep that expiration date in mind so you can use it before it’s gone!

Books / Products

Standard shipping is included in the price of the product you’re purchasing.  We ship out using MEDIA MAIL from the US Postal Service. Most people receive their order within 1-2 weeks (5-10 business days), depending on their location and local weather conditions. Orders shipped Media Mail are NOT tracked (unless you’ve ordered 3+ books). If you need products more quickly, you can upgrade to Expedited Shipping for an additional fee.

Expedited Shipping can mean one of several methods of shipment. If you want to have your product order sent to a PO Box, expedited shipping would be Priority Mail from the US Post Office. If you’re planning to ship to a street address, your expedited shipping options include Fed Ex Ground, Fed Ex 2nd day or Fed Ex Overnight. These methods are trackable. You must specify this premium service when you place your order. There are additional charges for expedited shipping.

You have several options in ordering products from OASIS Answers.  There is an order form in the back of your prior version of the INSTANT book that you can fill out and fax or mail in.  You may place an order on our website in the “Products” section.  You may call the office at 425-868-2304 and place your order over the phone.  The price for the INSTANT OASIS Answers book is $75 and includes shipping via US Mail.  Be sure to indicate whether you’d like a spiral bound or perfect bound book.

We don’t offer order fulfillment on PO.  We recommend that you print off the order form from the website and use that as an invoice to do a check request through your company’s Accounts Payable department.

You would need to contact us within 10 days of receipt to notify us that you wish to exchange the item(s).  Return shipment cost is the responsibility of the person/organization returning the item(s). Products must be in new, saleable condition with any plastic shrink-wrap still intact for it to be accepted for return. We can revise your order to include different products via the phone. Please be aware that there will be additional shipping charges incurred on the revised shipment. Those will be calculated at the time of order placement and added to your invoice. Any balance would be collected at the time the order is revised.

Products may be returned for a refund within 10 days of customer receipt. You would be responsible for the return shipping costs and, of course, the product must be in new condition with any plastic overwrap still intact. The initial shipping charges will not be refunded.  Refund will be credited to the initial payment method.

Our apologies if we sent a different product than you ordered. Please call us to let us know what happened, what product you ordered, what product you actually received. We will gladly research the transaction records to verify all the information. Rest assured that, if we erred, we will get the correct item to you right away. If the research indicates that you received what you ordered, you could return it at your expense as long as not more than 10 days had passed and the items was unopened with any plastic shrink-wrap still intact.  Shipping charges and any product price difference would be calculated for a replacement order and those would be collected at the time of re-order prior to the product shipping.

For the INSTANT OASIS Answers reference guides, a quantity discount affording $5 off per book is available for orders of 50+ books in a single transaction, shipped to a single location. There is currently no other discount structure for any other books or manuals.

Each year, the INSTANT OASIS Answers guide is updated and a lot of people look forward to having the most current, accurate information as quickly as possible. We accept pre-orders of the book and interested people may get in the queue to get their copy by processing a pre-publication order on our website, via fax or through the mail. As long as the book shows Pre-Publication/Pre-Order, it has not been finalized and is still a future product.  As soon as the new version of the book is available, we ship them out in the order that pre-publication orders were received.

It means that we’re waiting to get the latest updated version from the supplier. Normally, an estimated shipment timeframe is noted on the product’s description but if you would like to confirm, please feel free to contact us and we will try to get updated shipment dates for you.

Exam Questions

Taking the test and earning the designation shows a level of competency with the OASIS Data Set.  Your employer may require the test, internal promotions and career success may hinge on successful test results.  The COS-C Exam is the premier nationally standardized, psychometrically validated test that evaluates a clinician’s knowledge of CMS’ OASIS guidelines.

Because our exam is psychometrically validated, we never publish the passing score. The results are reported as pass/fail only. All results, pass or fail, are mailed approximately 2-3 weeks after a Pencil/Paper exam. Results on a computer-based exam will be given to you before you leave the testing center.

OASIS Answers follows industry-standard best practices and provides unsuccessful candidates with feedback after their test. Feedback is useful for finding out how to improve your test performance next time. While you will not receive details on each question in your test, you will be given feedback on your performance in each of the content areas covered by the examination.

OASIS Answers Inc. employs specialists in the branch of psychology that deals with the design, administration, and interpretation of quantitative tests for the measurement of psychological variables such as intelligence and aptitude. The power of psychometric testing is that there is a strong correlation between test scores and job performance, i.e. if you score highly on the COS-C psychometrically validated test, the chances are that you are going to perform well on the job.

We send your registration information to our partner, PSI Services. Wait 3-5 business days for the registration to be processed by PSI. You will then receive an eligibility confirmation email from PSI with instructions to schedule the exam. You will be able to select a date and make the exam appointment. 

Paper and Pencil exam results will not be shared over the phone or by email. P&P exam results will be scored and mailed to you within 2-3 weeks of the exam date. Results for a computer-based exam will be shown to you on the screen and also emailed to you after completion of the exam.

OASIS Answers maintains a database of those individuals who are active COS-C designees. You are welcome to check the COS-C listing on our website. The COS-C database is updated regularly but there is a 60 day lag time after an individual takes the exam for their passing status to appear on the database.

Only you can decide if you are ready to take the exam. Review the sample questions on the website (exam tab/prep resources) and determine for yourself if you feel comfortable with your knowledge base.

Although the Blueprint for Oasis Accuracy workshop is helpful, it’s your decision whether or not to take the class before you sit for the exam.

The COS-C exam does not require the tester to assign ICD-10-CM codes to any diagnosis. Potential questions on the exam would be limited to the knowledge necessary to complete the diagnosis related items of OASIS accurately which is found in Chapter 3 of the OASIS Guidance Manual and the related Q&As.

To protect the integrity of the exam, there are no complimentary retake options.

You can travel to another Blueprint for OASIS Accuracy class location and take a Pencil/Paper exam ($200 renewal / $250 initial candidates). Computer-based testing (CBT) is always an option as well. The exam can be taken at one of the many H&R Block testing centers around the country, on a day that is convenient for you. The CBT will cost you $95 more than a Pencil & Paper exam.

Exam registration fee is non-refundable. If OAI is notified of a candidate’s inability to sit for paper & pencil exam PRIOR to the exam date, we will issue a credit on the account. Credit is valid for 12 months and can be used for future exam date or any other OAI product or service. P&P exam registration can also be transferred to another candidate within the same organization for no additional fee. There is NO refund or credit for No Shows.  

For Computer Based Testing: Candidate has 12 months from the date of registration to schedule and sit for the COS-C Exam through PSI. Candidate will schedule directly with PSI. Candidate may reschedule test once without penalty (must be at least 48 hours prior to the scheduled appointment time). If exam appointment is canceled outside the allowed time period of the scheduled test date, candidate may reschedule with a $95 administrative fee.

Quarterly OASIS Update Teleconferences

When you or your agency purchase LIVE participation, you are purchasing one login for the event. This means that you may access the Quarterly update from a single location for the duration of the event. You can, for instance, have as many people as you wish around a conference table or in a meeting room using the one login. If you have many different locations or if you have people who work from home or in alternate areas it may be a better fit to purchase the RECORDED version of the Quarterly OASIS Update which can be shared with as many individuals within the local agency as necessary. Please be aware that access to the event is monitored and matched to the purchases made of the LIVE event.  If it is found that an agency has accessed from multiple locations, having purchased only a single login, you will be invoiced for the additional logins at the regular $199 per event charge.

We plan to have the session delivered within 24 hours of the event’s conclusion. We send out an email including the access link and all associated handouts as soon as the recorded version is available. Typically you will have your handouts and begin to access the Update before the close of business the day following the call.

The RECORDED version is delivered via an access link to our webinar platform. An email is sent containing the access link as soon as it is available.

The files may be large and can cause email delivery issues. If you are having problems accessing the files, please contact our office at 425-868-2304 or send an email to We can typically share a link and then you can download at will.  Occasionally, clients will need to access the file from a personal computer (not behind an office firewall).

First, please call the office at 425-868-2304 to verify that your email address is correct in our files. Our process includes providing Quarterly OASIS Update attendees credentials prior to the call (for LIVE participation) along with a link to access the handouts. 

Please call the office at 425-868-2304 and we will verify your email and order information.


You can call or email us to express your initial interest in private training.  We will then do a basic screening, review costs, responsibilities and typically ask the following questions:

    • What type of training are you interested in (OASIS, Hospice, Star Rating etc)?
    • In what city would the class be held? 
    • How many people are you thinking of training?
    • What is your time frame for holding the training?
    • What is the name and contact information for the program coordinator for your group?
    • Who would sign the contract and what is their contact information?
    • Do you have a venue in mind?

We would then compare calendars and select a couple of acceptable dates.  Once dates are confirmed, a contract would be signed and then program materials would be shared.

If your agency sends five or more people to a single workshop, you are eligible for a 10% discount from the current rate per person. If your organization is sending 11 or more people, the discount increases to 20% off the current rate per person. To register with this volume discount, please contact our office at 425-868-2304 and we’d be happy to help get everyone registered. This discount applies to the COS-C Conference, Blueprint for OASIS Accuracy and Hospice Item Set (HIS) workshops.

If it is more than 30 days prior to the workshop date, we can issue a refund to the original payment source, minus a 10% fee. Unfortunately, there are no refunds on workshop fees if it is within 30 days of the workshop start date. We would be happy to issue a credit though, minus a $150 administrative fee, to your account. With a written request, we can transfer your registration to another OAI-sponsored program, which also incurs a $150 administrative fee.

The credit is good for 12 months from the original event date and can be used on any product, workshop, teleconference or exam listed in our web store. Remember that you can send a colleague from your agency/company in your place without incurring any fees.  

You are welcome to register for a future workshop and we would look forward to seeing you there. Unfortunately, if we weren’t notified prior to the workshop start date that you would not be attending, no credit for that registration can be extended to you.

The Blueprint class is not a beginner’s course but no true “beginner” course is offered.  To be able to understand the course materials, you should familiarize yourself ahead of time.  Review the items under “OASIS Resources” on our website.  Especially focus on the Guidance Manual, Chapter 3 and all of the Q&A’s.   

The Blueprint for OASIS Accuracy workshops are for anyone who deals with OASIS in the home health industry. Nursing contact hours are available for this program.
