Student Name:________________________________________________________
School Name: ______________________________________________________________
Print your name and the name of your school on the lines above.
A separate answer sheet for Part I has been provided to you. Follow the
instructions from the proctor for completing the student information on your answer
sheet.
This examination has four parts, with a total of 39 questions. You must answer
all questions in this examination. Record your answers to the Part I multiple-choice
questions on the separate answer sheet. Write your answers to the questions in
Parts II, III, and IV directly in this booklet. All work should be written in pen, except
graphs and drawings, which should be done in pencil. Clearly indicate the necessary
steps, including appropriate formula substitutions, diagrams, graphs, charts, etc.
The formulas that you may need to answer some questions in this examination are
found at the end of the examination. This sheet is perforated so you may remove it
from this booklet.
Scrap paper is not permitted for any part of this examination, but you may use
the blank spaces in this booklet as scrap paper. A perforated sheet of scrap graph
paper is provided at the end of this booklet for any question for which graphing may
be helpful but is not required. You may remove this sheet from this booklet. Any
work done on this sheet of scrap graph paper will not be scored.
When you have completed the examination, you must sign the statement printed
at the end of the answer sheet, indicating that you had no unlawful knowledge of the
questions or answers prior to the examination and that you have neither given nor
received assistance in answering any of the questions during the examination. Your
answer sheet cannot be accepted if you fail to sign this declaration.

SCORING KEY AND RATING GUIDE
Mechanics of Rating
The following procedures are to be followed for scoring student answer papers for the
Regents Examination in Integrated Algebra. More detailed information about scoring is
provided in the publication Information Booklet for Scoring the Regents Examinations in
Mathematics.
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.
Unless otherwise specified, mathematically correct variations in the answers will be allowed.
Units need 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 mathematics
teachers. No one teacher is to score more than approximately one-third of the open-ended
questions on a student’s paper. Teachers may not score their own students’ answer papers.
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 this
exam 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 and
that the resulting scale score has been determined accurately.
Raters should record the student’s scores for all questions and the total raw score on the
student’s separate answer sheet. Then the student’s total raw score should be converted to a
scale score by using the conversion chart that will be posted on the Department’s web site
at: http://www.p12.nysed.gov/assessment/ on Wednesday, June 12, 2013. Because scale scores
corresponding to raw scores in the conversion chart may change from one administration to
another, it is crucial that, for each administration, the conversion chart provided for that
administration be used to determine the student’s final score. The student’s scale score
should be entered in the box provided on the student’s separate answer sheet. The scale score
is the student’s final examination score.
Integrated Algebra Rating Guide – June ’13 [2]
If the student’s responses for the multiple-choice questions are being hand scored prior to being
scanned, the scorer must be careful not to make any marks on the answer sheet except to record
the scores in the designated score boxes. Marks elsewhere on the answer sheet will interfere with
the accuracy of the scanning.

Updated information regarding the rating of this examination may be posted on the New
York 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 any
recently posted information regarding this examination. This site should be checked before
the rating process for this examination begins and several times throughout the Regents
Examination period.
Beginning in January 2013, the Department is providing supplemental scoring guidance,
the “Sample Response Set,” for the Regents Examination in Integrated Algebra. This
guidance is not required as part of the scorer training. It is at the school’s discretion to
incorporate 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
Sample Response Set illustrate how less common student responses to open-ended questions
may be scored. The Sample Response Set will be available on the Department’s web site at
http://www.p12.nysed.gov/assessment/scoring/home-hs.html.
Integrated Algebra Rating Guide – June ’13 [3]
General Rules for Applying Mathematics Rubrics
I. General Principles for Rating
The rubrics for the constructed-response questions on the Regents Examination in Integrated Algebra are
designed to provide a systematic, consistent method for awarding credit. The rubrics are not to be
considered all-inclusive; it is impossible to anticipate all the different methods that students might use to
solve a given problem. Each response must be rated carefully using the teacher’s professional judgment and
knowledge of mathematics; all calculations must be checked. The specific rubrics for each question must be
applied consistently to all responses. In cases that are not specifically addressed in the rubrics, raters must
follow the general rating guidelines in the publication Information Booklet for Scoring the Regents
Examinations in Mathematics, use their own professional judgment, confer with other mathematics
teachers, and/or contact the State Education Department for guidance. During each Regents Examination
administration period, rating questions may be referred directly to the Education Department. The contact
numbers are sent to all schools before each administration period.
II. Full-Credit Responses
A full-credit response provides a complete and correct answer to all parts of the question. Sufficient work
is shown 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 for
solving the question (usually introduced by the phrase “such as”), it does not mean that there are no
additional acceptable methods of arriving at the correct answer. Unless otherwise specified, mathematically
correct alternative solutions should be awarded credit. The only exceptions are those questions that specify
the type of solution that must be used; e.g., an algebraic solution or a graphic solution. A correct solution
using a method other than the one specified is awarded half the credit of a correct solution using the
specified method.
III. Appropriate Work
Full-Credit Responses: The directions in the examination booklet for all the constructed-response questions
state: “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 answer
was ob
