FOR TEACHERS ONLYThe University of the State of New YorkREGENTS HIGH SCHOOL EXAMINATIONINTEGRATED ALGEBRATuesday, January 22, 2013 — 9:15 a.m. to 12:15 p.m., onlySCORING KEY AND RATING GUIDEMechanics of RatingThe following procedures are to be followed for scoring student answer papers for theRegents Examination in Integrated Algebra. More detailed information about scoring isprovided in the publication Information Booklet for Scoring the Regents Examinations inMathematics.Do not attempt to correct the student’s work by making insertions or changes of any kind.In scoring the open-ended questions, use check marks to indicate student errors. Unlessotherwise specified, mathematically correct variations in the answers will be allowed. Unitsneed not be given when the wording of the questions allows such omissions.Each student’s answer paper is to be scored by a minimum of three mathematicsteachers. No one teacher is to score more than approximately one-third of the open-endedquestions on a student’s paper. On the student’s separate answer sheet, for each question,record the number of credits earned and the teacher’s assigned rater/scorer letter.Schools are not permitted to rescore any of the open-ended questions on thisexam after each question has been rated once, regardless of the final exam score.Schools are required to ensure that the raw scores have been added correctly andthat the resulting scale score has been determined accurately.Raters should record the student’s scores for all questions and the total raw score onthe student’s separate answer sheet. Then the student’s total raw score should be converted toa scale score by using the conversion chart that will be posted on the Department’s web siteat: http://www.p12.nysed.gov/assessment/ on Tuesday, January 22, 2013. Because scale scorescorresponding to raw scores in the conversion chart may change from one administration toanother, it is crucial that, for each administration, the conversion chart provided for thatadministration be used to determine the student’s final score. The student’s scale score shouldbe entered in the box provided on the student’s separate answer sheet. The scale score is thestudent’s final examination score.

Integrated Algebra Rating Guide – January ’13 [2]If the student’s responses for the multiple-choice questions are being hand scored prior to beingscanned, the scorer must be careful not to make any marks on the answer sheet except to recordthe scores in the designated score boxes. Marks elsewhere on the answer sheet will interfere withthe accuracy of the scanning.Part IAllow a total of 60 credits, 2 credits for each of the following.Updated information regarding the rating of this examination may be posted on the NewYork State Education Department’s web site during the rating period. Check this web site at:http://www.p12.nysed.gov/assessment/ and select the link “Scoring Information” for anyrecently posted information regarding this examination. This site should be checked beforethe rating process for this examination begins and several times throughout the RegentsExamination period.Beginning in January 2013, the Department is providing supplemental scoring guidance,the “Sample Response Set,” for the Regents Examination in Integrated Algebra. Thisguidance is not required as part of the scorer training. It is at the school’s discretion toincorporate it into the scorer training or to use it as supplemental information during scoring.While not reflective of all scenarios, the sample student responses selected for the SampleResponse Set illustrate how less common student responses to open-ended questions may bescored.

Integrated Algebra Rating Guide – January ’13 [3]General Rules for Applying Mathematics RubricsI. General Principles for RatingThe rubrics for the constructed-response questions on the Regents Examination in Integrated Algebra aredesigned to provide a systematic, consistent method for awarding credit. The rubrics are not to beconsidered all-inclusive; it is impossible to anticipate all the different methods that students might use tosolve a given problem. Each response must be rated carefully using the teacher’s professional judgment andknowledge of mathematics; all calculations must be checked. The specific rubrics for each question must beapplied consistently to all responses. In cases that are not specifically addressed in the rubrics, raters mustfollow the general rating guidelines in the publication Information Booklet for Scoring the RegentsExaminations in Mathematics, use their own professional judgment, confer with other mathematics teachers,and/or contact the State Education Department for guidance. During each Regents Examinationadministration period, rating questions may be referred directly to the Education Department. The contactnumbers are sent to all schools before each administration period.II. Full-Credit ResponsesA full-credit response provides a complete and correct answer to all parts of the question. Sufficient work isshown to enable the rater to determine how the student arrived at the correct answer.When the rubric for the full-credit response includes one or more examples of an acceptable method forsolving the question (usually introduced by the phrase “such as”), it does not mean that there are noadditional acceptable methods of arriving at the correct answer. Unless otherwise specified, mathematicallycorrect alternative solutions should be awarded credit. The only exceptions are those questions that specifythe type of solution that must be used; e.g., an algebraic solution or a graphic solution. A correct solutionusing a method other than the one specified is awarded half the credit of a correct solution using thespecified method.III. Appropriate WorkFull-Credit Responses: The directions in the examination booklet for all the constructed-response questionsstate: “Clearly indicate the necessary steps, including appropriate formula substitutions, diagrams, graphs,charts, etc.” The student has the responsibility of providing the correct answer and showing how that answerwas obtained. The student must “construct” the response; the teacher should not have to search through agroup of seemingly random calculations scribbled on the student paper to ascertain what method the studentmay have used.Responses With Errors: Rubrics that state “Appropriate work is shown, but …” are intended to be used withsolutions that show an essentially complete response to the question but contain certain types of errors,whether computational, rounding, graphing, or conceptual. If the response is incomplete; i.e., an equation iswritten but not solved or an equation is solved but not all of the parts of the question are answered,appropriate work has not been shown. Other rubrics address incomplete responses.IV. Multiple ErrorsComputational Errors, Graphing Errors, and Rounding Errors: Each of these types of errors results in a 1-credit deduction. Any combination of two of these types of errors results in a 2-credit deduction. No morethan 2 credits should be deducted for such mechanical errors in any response. The teacher must carefullyreview the student’s work to determine what errors were made and what type of errors they were.Conceptual Errors: A conceptual error involves a more serious lack of knowledge or procedure. Examples ofconceptual errors include using the incorrect formula for the area of a figure, choosing the incorrecttrigonometric function, or multiplying the exponents instead of adding them when multiplying terms withexponents. A response with one conceptual error can receive no more than half credit.If a response shows repeated occurrences of the same conceptual error, the student should not be penalizedtwice. If the same conceptual error is repeated in responses to other questions, credit should be deducted ineach response.If a response shows two (or more) different major conceptual errors, it should be considered completelyincorrect and receive no credit.If a response shows one conceptual error and one computational, graphing, or rounding error, the teachermust award credit that takes into account both errors; i.e., awarding half credit for the conceptual error anddeducting 1 credit for each mechanical error (maximum of two deductions for mechanical errors).

Schools are required to ensure that the raw scores havebeen added correctly and that the resulting scale score has been determined accurately.Because scale scores corresponding to raw scores in the conversion chart change from one administration toanother, it is crucial that for each administration the conversion chart provided for that administration be used todetermine the student’s final score. The chart above is usable only for this administration of the Regents Examinationin Integrated Algebra.The State Education Department / The University of the State of New YorkRegents Examination in Integrated Algebra – January 2013Chart for Converting Total Test Raw Scores to Final Examination Scores (Scale Scores)To determine the student’s final examination score, find the student’s total test raw score in the column labeled “RawScore” and then locate the scale score that corresponds to that raw score. The scale score is the student’s finalexamination score. Enter this score in the space labeled “Scale Score” on the student’s answer sheet.Integrated Algebra Conversion Chart - January 13 1 of 1
