Certified Paraoptometric
Review Course
CPO
Provision
The Self Study Course for Paraoptometric Assistants and Technicians,
Self Assessment Examination, and the AOA PS CPO Review Course
are not prerequisites for taking the paraoptometric certification
examination given by the Commission on Paraoptometric Certification
(CPC). Using these study materials and/or taking the CPO Review
course does not guarantee passing the paraoptometric certification
examination given by the CPC. Attending the CPO Review Course is
not a substitute for studying for the paraoptometric certification
examination given by the CPC. This course is designed to review
previously acquired knowledge.
This review course is not intended to be a
substitute for responsible study and preparation for
the CPO test.

HIPAA
Minimum Necessary Principle
Requires office to take reasonable steps to limit the
use or disclosure of, and request for, PHI to the
minimum necessary to accomplish intended purpose
HIPAA
Implementing Standard
Identify those in your office who need access to PHI to
do their job
Further identify anyone else who may need access
Create policies and procedures for routine disclosures
to achieve purpose of disclosure
Limit the PHI disclosed by developing criteria
Review request on individual basis against criteria

A Little Anxiety Is Ok
How To Study
Become interactive with
material
flash cards
notes
tape record notes
study groups
Study environment
floral scented candles
or potpourri facilitates
learning (strange but
true)
wake up your body,
wake up your mind walk, sit on edge of
chair
How To Study
Study pace - preview material, study, break, review
Do not study for more than 2 hours at a time
Use travel time to study
Test Taking Tips
Get plenty of rest the
night before - important in
this meeting environment.
Arrive a little early for
test- look for test room
today.
A little anxiety is OK - it
makes us perform better.
Know the time limit and
be aware of time
throughout the test.
Manage your time.
Read the directions
carefully.
Test Taking Tips
Realize there may be
questions you do not know
the answer. There should
not be many but we tend to
remember them.
Your first impression for
an answer is usually the
best.
Memory dump - at
beginning of test write
down the facts you want to
remember.
Make a mark at the
margin on questions you
want to return to.
Multiple Choice Questions
Essentially are true/false questions arranged in groups.
Only one alternative is totally correct.
Eliminate obvious false choices.
Of remainder pick the alternative that answers most
fully all aspects of the question.
Only change your first answer if you have a very
good reason - i.e. read questions incorrectly.
What’s Next?
Today
Lightly review the material
Get a good night’s sleep
Arrive a little early to test
Future
Look for details about the CPOA test - begin
studying the Self-Study Course for Paraoptometric
Assistants and Technicians
