ISEE Lower Level Vocabulary

For students applying to grades 5–6.

What the test asks, 100 words to know, and how to study the rest.

How the Lower Level tests vocabulary

Vocabulary on the ISEE is tested in the Verbal Reasoning section: 34 four-option questions in 20 minutes at the Lower Level. Two question types share the section. Synonym questions give one word and ask for the closest meaning. Sentence completion questions give a sentence with a blank and ask which word fits it best — so knowing a definition is not enough; you need to know how the word is used.

Lower Level words are the vocabulary of good fifth- and sixth-grade reading: concrete, everyday-academic words such as “accumulate”, “boundary” and “cooperate”. Most name actions, feelings and qualities a student has met in a novel or a science lesson but may not yet use comfortably.
