TWI Settings Preference
You can use the TWI Settings Preference to specify that the students should always be asked how a book was read (Read To, Read With or Read independently), or you can choose to have the program automatically mark that the book was Read Independently.
The TWI Settings Preference is in the Quiz Settings preferences under Individual Student Preferences on the Preferences page.
How to change the TWI Settings Preference
If a student takes a Reading Practice quiz on a book read To or With, six months later he or she can retake the quiz if the book was read Independently.
