As of May 1, 2016, Prometric and the Washington Department of Health have enhanced the candidate application process in addition to introducing a new Knowledge Exam to certify Home Care Aides. Please visit DOH’s webpage HERE for more information

Take a practice test for the new knowledge exam that went live on May 1, 2016

ATTENTION: All Home Care Aide test takers and trainers!

A new certification law took effect in January 2012 that requires candidates of the Washington Home Care Aide program to follow some new guidelines in regards to their training and certification.

1. Complete a Washington State Department of Health application within fourteen days of hire.

The Department of Health (DOH) Application includes information required to schedule candidates for the certification exam. Prometric requires candidates to provide an email address to be scheduled for the certification exam. If an email address is not provided, Prometric will NOT schedule candidates to take the certification exam. Payment for the exam must be included along with the complete DOH application submitted to DOH. DOH will send the candidate an Authorization to Test email and notify Prometric once a candidate has met all requirements to take the certification exam.

2. Complete 75 hours of training.

The law now requires applicants to complete 75 hours of training before taking the exam. DOH will verify training is completed and notify Prometric that candidates can be scheduled for the certification exam.

3. Read the Candidate Bulletin.

The booklet contains important information about exam fees, scheduling and scoring, and includes a set of frequently asked questions to provide candidates with information and help simplify the process. Please download the booklet and read it!

4. Read the letter from Prometric.

Once Prometric receives notice from DOH that a candidate is eligible to take the certification exam, Prometric will email an Admission to Test (ATT) to the candidate’s e-mail address that was provided on the submitted application. It is the candidate’s responsibility to check their inbox, junk and spam folders for emails from Prometric. The ATT will provide important information about the time, date and location of the exam. This is the final step in the exam scheduling process. If the ATT has not been received after two weeks (30 days if requesting an interpreter or ADA accommodation) from receiving an Authorization to Test email from DOH, please contact Prometric.

5. Prepare for test day!

Arrive at the testing location on the date and time stated in the ATT email from Prometric. Candidates should bring the ATT and must bring two valid forms of ID to the testing location.

We hope this helps provide some guidance around the new process and helps test takers and trainers know what steps to take to have a positive testing experience.
