Conn. Gen. Stat. § 9-148: Counting of absentee ballots; training of counters.

The appointment of absentee ballot counters shall be made by the registrars of voters. The presiding officer for the purpose of declaring the result of the vote of the whole municipality is the moderator. Each person appointed to count absentee ballots shall participate in a training session at which the registrars of voters, absentee ballot moderator or moderator of the polling place, as the case may be, shall review and study the absentee counter's manual provided by the Secretary of the State under section 9-150a. Each elector so appointed shall be sworn to carry out faithfully the duties of his office and not to attempt to ascertain the manner in which any absentee elector has marked his absentee ballot. The registrars of voters shall ascertain the voting district in which each absentee elector is registered and shall apportion the envelopes according to voting districts among the appointed groups of electors, if there is more than one such group, in such manner that each group can conveniently count the votes apportioned to it.
