Toastmaster of the Meeting —  The Toastmaster is the "master of ceremonies" and leader of the meeting. The Toastmaster is responsible for administering the meeting and keeping it running on-time. The Toastmaster sometimes provides a word of the day and encourages meeting attendees to use the word. The Toastmaster sometimes has a quote or thought of the day. If meeting participants are advised in advance, this can become a theme for the meeting.
TopicMaster — The TopicMaster presides over the Table Topics (impromptu) section of the meeting. The TopicMaster prepares a set of unique questions and randomly calls on club members to respond. Guests may be invited to participate, but never directly called on. The Topicmaster should sit while each response is given so that the member addresses the audience and not the Topicmaster.
Hackettstown performs instant TableTopics Evaluations. After each TableTopic question is answered, the TopicMaster will call on an experienced Toastmaster to give a 15 to 45 second evaluation of the answer. Feedback is THAT important!
General Evaluator — The General Evaluator presides over the evaluation section of the meeting. The General Evaluator calls for reports by the Grammarian/Ah-Counter and the Timer and provides feedback on the meeting in general.
Speaker — Speakers give speeches they have prepared based on the Competent Communication manual, and they have objectives to meet for each speech. Most speeches are 5 to 7 minutes long. When a speaker has given 10 speeches, he/she earns the title of CC, Competent Communicator.
Evaluator — Each prepared speaker has an evaluator assigned to provide the speaker with feedback. The evaluator provides both written and oral feedback.
Ah-Counter / Grammarian — The Ah-counter/Grammarian monitors speakers and reports on both good and bad use of the English language. When speaking, people often use such 'crutch' words or fillers as ah, um, you know, well, and, or they just repeat a word or phrase. These words and sounds can be annoying to listeners. The Ah-Counter notes these words or sounds and helps the Speaker become aware of them.
Timer — One of the purposes of Toastmasters is to teach people to express thoughts within a specific time interval. The Timer is responsible for monitoring time and emphasizing the importance of time to everyone. Each segment of the meeting is timed. The Timer operates the timing lights or colored cards that indicate to the Speaker how long he or she has been talking. A green light is turned on when the speaker has met the miniumum time requirement. A yellow warning light is turned on to indicate that thje speaker should wrap up. A red light is turned on when the speaker has reached the maximum time limit for their speech.

Toastmasters chapters MAY use these roles:

Word of the Day — The Word of the Day is used to improve the vocabulary of the club. Each meeting a member of the club introduces a word, defines it, and gives an example of its usage. Members attempt to use the word during their speeches.
Sergeant-at-Arms — The Sergeant-at-Arms is responsible for the set-up and tear-down of the room as well as opening the meeting by calling the meeting to order and introducing the Toastmaster of the day. It is the Sergeant at Arms' responsibility to ensure that meetings start on-time.
Joke Master — The Joke Master warms up the audience or sends it home laughing by delivering a (tasteful) joke that should reflect the Toastmaster’s theme of the meeting.
Pledge / Inspiration —  This member leads the Pledge of Allegiance and then delivers a brief message of inspiration.
Invocator —  The Invocator delivers a brief invocation to open the meeting.
