Let Us Help You Understand...

When applying for certain positions, you might be required to take the TSA CBT test, which consists of two sections: The Written Skills Test (or English Test) and the X-ray Image Interpretation Test.

The first section usually consists of 60 questions and is used to evaluate your skills in areas such as punctuation, spelling, capitalization, and similar. It is divided into three categories, which are Vocabulary, Reading Comprehension, and Written Communication.

In this article, we will help you prepare for the test and get as higher a score as possible! You will also see what to expect from the test and what it basically looks like.

TSA CBT Vocabulary

Vocabulary is designed to evaluate your level of English, and although questions might appear simple at first, they can actually be quite complicated.

Questions usually require replacing synonyms and antonyms in a sentence or correcting minor spelling mistakes. So, let’s start with synonyms!


A synonym is a word or phrase that has the same or very similar meaning to another word or phrase. Let’s take a look at the following sentence:

“We need to talk about this important issue immediately.”

Which of the following answers would be the appropriate replacement for the word written in bold?

The correct answer is Critical since Important and Critical are synonyms.


An antonym is a word of opposite meaning to another word. Take a look at the following sentence:

“The speaker was unable to pacify the crowd.”

Which of the following answers is the opposite of the one written in bold?

The correct answer is Excite since Excite and Pacify are antonyms.

Tips and Tricks

To improve your vocabulary, it is essential to read a lot, which is also the best way to learn the meaning of different words. No matter if you read books or newspapers, you will learn many words that you don’t use on a daily basis.

Another great way to improve your vocabulary is to practice vocabulary exercises, which you can find in our new Compass Exam Preparation Course. It will definitely sharpen your skills and help you achieve a much better score.

Just passed my test! Great prep course, it definitely prepared me and gave a great insight on what to expect on the test.

TSA CBT Reading Comprehension

This category includes a paragraph of varying length, followed by a question with four optional answers. The questions are used to evaluate your understanding of the text and your level of English, but not your logical reasoning skills. There is a time limit, which is usually 90 seconds for each question.

A useful tip for passing this category more easily is to read the entire text before choosing the answer. However, if the paragraph is short, it might help to read the questions first, since it will give you an insight into what is the text about.

TSA CBT Written Communication

This category of the test is very broad and may contain different kinds of questions. It is designed to evaluate your skills in areas such as English grammar, spelling, and punctuation. To score as good as possible in this category, it is essential to refresh your knowledge of grammar, syntax, usage, and organization of sentences and paragraphs.

Sentence Construction

A sentence is a grammatically independent group of words used to express something. Usually, the sentence contains a subject, which is a noun and/or pronoun, and a predicate, that consists of at least one verb.

However, even the single word “Go!” is considered a sentence. That sentence theoretically doesn’t contain a subject, but it has an implied subject, which is the person to whom is being directed to go, and it still contains a verb.

Use of Phrases and Clauses

A group of related words that contains no subject, and in some cases even no predicate,
is called a phrase. There are five different types of phrases, which are gerund, infinitive, participle, prepositional, and verb phrases.

Clauses, on the other hand, are grammatical units that contain both the subject and the verb and can be dependent or independent. The first type of clause cannot stand alone as a sentence, and could be something like “As he was smiling”. An Independent clause can stand alone as a sentence, and a good example would be “He laughed”.
Notice that the independent clause expresses the main thought of the sentence, while the dependent clause expresses the idea that is not as important as the idea expressed in the main clause. That is why it can’t stand alone as a sentence.

Restrictive and Nonrestrictive Phrases and Clauses

A restrictive clause or phrase gives us the information that is necessary to identify what is specifically being described. On the other hand, a nonrestrictive phrase or clause provides information that is of less importance to the meaning of the sentence.

Take a look at the following sentences:

In the first example, the clause “who won the match” is essential for indicating the person who should be congratulated. In the second example, the person who deserves congratulations is identified as Mark, so the clause “who won the match” is not essential for identifying the person.

Another thing you should notice is that, generally, restrictive phrases and clauses are NOT separated by commas from the rest of the sentence. Nonrestrictive phrases and clauses, on the other hand, are separated by commas.


A verb is a word or phrase that asserts an action or a state of being. Verbs can have two voices (active and passive), which show whether the subject performs or receives an action. For example:

Verbs also have a tense, which shows the time of the action of the verb. Let’s see the differences between the six tenses.

Verbs also have a mood, which shows whether the action is a fact, a command, or something other such as a possibility or a wish. If the action is a fact, the mood is indicative, while if it is something other than the fact, the mood is subjunctive. If the action is a command, the mood is imperative.

Verbs can have forms, such as infinitive, gerund, and participle. An infinitive is the form of a verb that expresses action without reference to a specific person or tense, for example: To walk is relaxing.

A gerund is a form of a verb used that ends in “ing” and is used as a noun. For example, Singing was her favorite activity.

A participle is a form of the verb used as an adjective and usually ends in “ed” or “ing”. A good example would be: My birthday party was exciting!

Totally Worth Buying this Course!

I bought this course 3 days before taking the CBT test. It truly helped me. The X-ray portions of this course will help you out tremendously by practicing them over and over. I took my test this morning and PASSED on the first try. I was worried because I didn’t wanna wait 6 months to take the test again.

Game Changer

I took and failed the TSA exam in April of 2018. I bought this and took the exam again in Jan 2020 and passed. The first time i took the exam i had no idea there would over 100 xray pictures to look at. I knew I needed up when I signed up to take the test again. This guide was the differnece in me passing the exam. Worth every Penny

Nouns and Pronouns

According to definition, a noun is a word that names a place, person, thing, quality, action, or idea. Now, there are different types of nouns, so let’s check them out!

The possessive of a singular noun is written by adding an apostrophe and “s” at the end of the noun, while the possessive of a plural noun ending with “s” is formed by adding only an apostrophe at the end.

For example: the boy’s sweater, Mike’s truck, workers’, employers’, and similar.

Pronouns are used in a place of a noun, usually to prevent a monotonous repetition of the noun. There are eight types of pronouns:

Adjectives and Adverbs

Simply put, an adjective is a word that describes a noun, while an adverb modifies a verb, another adverb, or adjective. For example: A beautiful lady is slowly approaching.

Both adjectives and adverbs show a certain degree of quality or quantity and can be in a positive, comparative, or superlative form. For example: long, longer, longest.

Prepositions and Conjunctions

A preposition is a word that connects a noun to some other word. For example: in two months, after several years, and similar. There are over 40 prepositions in English, including: at, below, for, from, about, around, to, up, etc.

A conjunction is a word that joins together sentences, words, or phrases. Some examples include: and, but, or, nor, for, yet, either, neither, both, etc.

Paragraph Organization

These exercises are designed to evaluate your ability to organize sentences into paragraphs. For example, take a look at these four sentences:

What would be the most appropriate and effective ordering of the sentences above? The answer is a-d-b-c.

Sentence Completion

This part of the test evaluates your ability to complete a sentence that is missing one or more words, while the propositions include misspelling and grammatical errors. One of the best ways to prepare for this part is to complete similar exercises on a daily basis. That way, you will easily remember different tenses and spelling rules.
