RULES REGARDING: 

LABORATORY EXPERIENCE

Admission of the student into a Regents examination in aScience is certification that the laboratory work is complete.  Completion implies a satisfactory report ofthe laboratory work; without such a report, much of the value of the laboratorywork is lost.  A deficiency here meansthat the course in not completed and the student concerned should not beadmitted to the Regents Examination.

Please note that in order to get credit for this Regentscourse, you must write a satisfactory laboratory report for each experimentperformed.  If this is not done you willnot be able to take the Regents and on your transcript you will receive a  “0” for the Regents grade.  This will be averaged in to determine yourfinal grade for the course.

N.Y.S. Education Law requires a laboratory notebook orfolder.  This notebook or folder shouldcontain all your laboratory reports.  InChemistry, student lab reports will be kept in folders by the teacherthroughout the year.
