Conn. Gen. Stat. § 10-15b

(b) The parent or legal guardian with whom the student does not primarily reside shall be provided with all school notices that are provided to the parent or legal guardian with whom the student primarily resides. Such notices shall be mailed to the parent or legal guardian requesting them at the same time they are provided to the parent or legal guardian with whom the child primarily resides. Such requests shall be effective for as long as the child remains in the school the child is attending at the time of the request.

(c) If any private or public school is served with a subpoena issued by competent authority directing the production of school or student records in connection with any proceedings in any court, the school upon which such subpoena is served may deliver such record or at its option a copy thereof to the clerk of such court. Such clerk shall give a receipt for the same, shall be responsible for the safekeeping thereof, shall not permit the same to be removed from the premises of the court and shall notify the school to call for the same when it is no longer needed for use in court. Any such record or copy so delivered to such clerk shall be sealed in an envelope which shall indicate the name of the school or student, the name of the attorney subpoenaing the same and the title of the case referred to in the subpoena. No such record or copy shall be open to inspection by any person except upon the order of a judge of the court concerned, and any such record or copy shall at all times be subject to the order of such judge. Any and all parts of any such record or copy, if not otherwise inadmissible, shall be admitted in evidence without any preliminary testimony, if there is attached thereto the certification in affidavit form of the person in charge of such records indicating that such record or copy is the original record or a copy thereof, made in the regular course of the business of the school, and that it was the regular course of such business to make such record at the time of the transactions, occurrences or events recorded therein or within a reasonable time thereafter. A subpoena directing production of such school or student records shall be served not less than eighteen hours before the time for production, provided such subpoena shall be valid if served less than eighteen hours before the time of production if written notice of intent to serve such subpoena has been delivered to the person in charge of such records not less than eighteen hours or more than two weeks before such time for production.
