Both the SAT and ACT exams test students’ knowledge of where commas should be placed in a list. Unless a list is only two items long, commas should separate items, including the one before “and.”

A list can contain many types of phrases, or a combination of phrases, but items in the list should always maintain the same structure:

How often has it appeared on
recent exams?
Type of
SAT: 7 times
ACT: 1 time
Noun phrasesThe storm brought with it cold winds, large hail, and great floods.
SAT: 2 timesParticiple phrasesHe has had many jobs including busing tables, bagging groceries, and washing cars.
SAT: 1 timePrepositional phrasesI have looked for my phone everywhere: in my car, on the counter, and under my bed.
SAT: 1 timeNouns plus prepositional phrasesThe poem contained lines with alliteration, instances of metaphors, and allusions to the Bible.
SAT: 1 timeInfinitive phrasesTeens seek to become self-sufficient, decrease their parents’ authority, and control their own destinies.
ACT: 1 timeIndependent clausesMy cousin left for college, my uncle went on a business trip, and my aunt stayed home.
ACT: 1 timeAdjectivesHis small, red ball is lost = His small and red ball is lost.

The only time a comma will separate two listed items is when it takes the place of the word “and” between two adjectives as in the example in the chart above.
