Convergence Insufficiency (CI)

The Assessments:  Convergence Insufficiency

Convergence Insufficiency (CI) Symptom Survey:

This is a standardized test that has proven to identify CI, the most common vision disorder that delays the acquisition of reading skills. It occurs in approximately  83% of kids who are reading behind their grade level in school. (Journal of Optometric Visual Science, 2009)

The CISS test takes about 20 minutes to complete.


It’s best to administer the test in a quiet room with no distractions.  Your child should be rested.

Read each question out-loud to your child and record the child’s answers on the test grid.
Do not prompt your child for an answer and don’t explain what the question means.  Usually, if your child experiences what the question is asking, they will understand exactly what is being asked and they won’t need further explanation.

At the end of the test, click on CHECK SCORE to see the final score and recommendations on how to proceed.  *** if your score does not come up it most likely means that you have missed filling in a bubble.  Check to make sure that every question has been answered.

Then, click the link “Proceed to next Assessment”.

Also, click:  “Solution: Online Therapy” to learn how to relieve the symptoms of CI.

You can return to the Assessments at any time by using the side menu “Assessments” under the testing category you are wishing to return to.

If you should get interrupted in the middle of the test and have to stop, no worries!  When you return, you’ll need to begin this test at the beginning but you can return to the website as many times as you’d like for 90 days by using your LOG IN info.
