Description of the Daze Measure

Daze, or the DIBELS maze comprehension task, is a group-administered measure of reading comprehension.  Students are asked to read a passage silently. In the passage, every seventh word (approximately) is blank, with a maze of options (i.e., three possible word choices for the blank). One of the words in the maze is always correct, and the other two are incorrect. Daze requires students to choose the correct word as they read the passage. Students are given three minutes to work on this task. The score is the number of correct words circled minus half of the number of incorrect words circled.

Differences between the 6th and Next Editions of Daze

Daze is not available with DIBELS 6th Edition.

How does Daze link to the Big Ideas in Beginning Reading?

Daze is a measure that assesses reading fluency and reading comprehension. Daze is a reading fluency task in that student responses are timed for three minutes, and the stronger a reader the student is, the more maze items they will encounter in that three minute timing. Daze is also an indicator of reading comprehension, as completing the maze task requires students to understand what they are reading.
