Student Edition, a test-taking product. It reads the test aloud and allows students to answer the questions.

Try out the test as the student will.

We recommend that you use TestTalker Teacher Edition following the steps below.

Open TestTalker.
Scan, open, or import a test, form, or worksheet into TestTalker.
Check the reading order. Use Dynamic Zoning to re-define OCR zones to change the reading order if desired. It is important that this be completed prior to steps #4 and #5, or else changes made during those steps will be lost when TestTalker’s OCR software re-recognizes the document (see Dynamic Zoning Tips for more information).
Clean up any errors in scanning using the Clean-Up button.
Insert answer blanks for Fill-in, Extended Answer, Multiple Choice, and True/False.
Check the answer blanks in the test, form, or worksheet, as a student would, using Student Mode.
Erase answers you may have added while checking out the test. You may want to print this out first to use it as an answer key.
Save material to disk or other place where students have access.

Use the Student Edition to:

Open a test that has been prepared in the Teacher Edition.
Complete the test or worksheet by typing your answers into the fill-in blanks, or clicking on the multiple choice or true/false buttons.
Read the test aloud, including both the questions and the answers the student has added.
Save and print the test when completed.
