Ever noticed how a single missing word can change the entire meaning of a sentence?
That’s the challenge—and the beauty—of the Sentence Completion section in the CogAT Grade 8 Verbal Battery.
In this section, students are asked to choose the word or phrase that best completes a sentence logically and grammatically. It’s not just about knowing vocabulary—it’s about understanding context, tone, and relationships between ideas. These questions reveal how well your child can read between the lines and grasp meaning beyond individual words.
The Gifted CogAT Test Prep App helps students strengthen this exact skill through structured Sentence Completion practice for Grade 8. Each question is carefully designed to mirror the real CogAT format, training your child to think critically about how words and ideas connect.
We’ve included 10 free CogAT Sentence Completion practice questions for Grade 8 below. These questions reflect the same reasoning, vocabulary range, and difficulty level your child will face on test day. Use them to evaluate how effectively your child understands sentence structure and context clues.
