# Quantitative Validation Exams

##### Who needs to take the quantitative validation exams?

Any MPAff student who has not successfully completed (with a grade of "C" or better), at least one semester of statistics and one semester of calculus, at the undergraduate level. (Note: There are two validation exams, one for statistics and one for calculus. You need take only the exam for which you have not had an undergraduate course. Basic algebra skills are a must, and are included in both statistics and calculus courses and exams.) If you are unsure about whether or not you should plan to take the exam, contact the Admissions Coordinator.

See the MPAff Quantitative Prerequisites for specific information about how to determine your needs.

##### How do I let you know I've completed statistics and/or calculus at the undergraduate level?

If you have one semester (at least 3 credit hours, or equivalent) of a basic statistics and/or calculus listed on the transcript(s) used to apply to the LBJ School, then we already know that you've met that requirement. No further action is necessary on your part.

If you are unsure whether or not a particular course on your undergraduate transcript satisfies the statistics and/or the calculus requirements, contact the Admissions Coordinator.** **The LBJ School requires all transcripts for undergraduate work whether or not those courses were used towards graduation. If the course title is not plain - such as Basic Statistics 101 - then you may want to check with us.

If necessary, the Graduate Adviser may require further information from you in order to determine if you've satisfied the quantitative prerequisites.

- The name and number of the course in question, as listed on your transcript.
- A brief description of the course (usually from the school catalog), and
- Either a syllabus from the course, or the title and author(s) of the text used in the course, (indicating which chapters were covered by the course), as well as
- Some proof of the grade received in the course, such as a transcript copy, grade report, etc.

##### If I don't have either statistics or calculus, or both, on an undergraduate transcript, am I required to take the validation exam(s)?

Yes! You must demonstrate proficiency in statistics and calculus, either through successful completion of an undergraduate course in the subject(s), or by passing the validation exam for each subject, before you will be allowed to register for IEM.

##### What is the best way to satisfy the statistics proficiency requirement if I haven't taken any undergraduate statistics courses?

Historically, self-study has not been a successful way of preparing for the validation exam. We strongly recommend that you consider taking an undergraduate course in statistics from a local community college or undergraduate institution, this is the best way to prepare for IEM (PA 397). This course should include concepts such as descriptive statistics, hypothesis testing, and an introduction to regression modeling. Successful completion of this course (with a grade of "C" or better) means that you do not need to take the statistics validation exam.

The LBJ School offers a undergraduate course that satisfies both the statistics and calculus requirements. The course is normally offered during the 1st summer term (June through the middle of July). Unfortunately, for newly admitted students neither financial aid nor fellowships awarded to begin in the fall semester will not be available for use.

##### Do I really need to take, or have undergraduate credit for, a full semester of calculus to satisfy the pre-requisites?

Not really. IEM and other "quantitative" courses at the LBJ School require familiarity with the concepts of differential calculus (derivatives and optimization). Integral calculus, which is usually included in a one semester undergraduate calculus course, is not required to successfully complete the LBJ quantitative courses. You can learn the requisite differential calculus concepts through a variety of means such as internet courses, short courses, self-study, etc. * However, you will still be required to demonstrate your proficiency in differential calculus by taking, and passing, a validation exam*.

##### Will an undergraduate course taken on the internet satisfy the requirement for a course in statistics and/or calculus?

Yes, you can use an internet course to meet your requirement for an undergraduate statistics course and/or an undergraduate calculus course as long the on-line course is from an "accredited" institution. Before you enroll in the online course, please send the following to the Admissions Coordinator to verify that it satisfies the prerequisite:

- A brief description of the course (usually from the school catalog), and
- Either a syllabus from the course, or the title and author(s) of the text used in the course, (indicating which chapters are covered by the course), as well as
- The URL for the course

**How do I prepare for the validation exams?**

Study! Do practice problems! You can do this in whatever way fits your learning style. If you don't take a formal undergraduate course in statistics and/or calculus, you can prepare/study for the validation exam by (1) studying the topic on your own using one or more recommended texts, (2) taking a short course on the internet or from any other source, (3) supplementing your study by attending Camp LBJ quantitative review sessions, or (4) forming informal study groups. (Note: Camp LBJ quantitative review classes are intended to be just that – "reviews." They are not intended to be introductory courses in statistics or calculus, nor are they necessarily intended to provide all that one needs to know to pass either validation exam.)

**When and where will the validation exams be given?**

##### You may take the exams on during new student orientation in August or on a date during the Fall semester to be determined.

How long will the validation exams take?

The exams are "proctored in-class" exams. A maximum of two hours are allowed for the statistics exam and two hours for the calculus exam.

##### What reference material can I use during the exam?

Both exams are Open notes / Open Book. You are welcome to bring any materials, books, calculators, computers, notes, etc. you'd like to use as reference. You should also bring a couple of pencils. We'll provide the scratch paper.

##### If I do not pass a validation, can I take it again?

Yes, but not the same day. No re-exams are allowed during August. You may retake the exam(s) on the tentatively scheduled dates in during fall or early January. Re-exams outside these dates are on an "exception only" basis.

##### When will I know if I passed the validation exam(s)?

We will notify you before registration. For exams taken in December or January, we will notify you of your status before the add/drop access period re-opens in January.

##### What if I take the validation exam(s) but don't pass it (or both)?

You won't be allowed to register for IEM (a required core course) until you pass the exam(s) or successfully complete an undergraduate course in that subject. (The Graduate Adviser can suggest some undergraduate courses that will help fulfill these requirements locally.)

**What if I need to take both exams, but pass only one of them?**

See the answer above. You must qualify in both statistics AND calculus.

**What is the effect of not passing the quantitative validation exams?**

You will not be permitted to take the two quantitative courses required for your MPAff unless you have satisfied the quantitative prerequisites. If you delay the start of your quantitative courses until your second year (fall semester) and you intend to take the Internship for credit, you will not have fulfilled all the requirements necessary to do your internship during summer. (Note: In order to register for your Internship course, you must have completed at least five of six "core" courses – i.e., Introduction to Empiral Methods, Advanced Empirical Methods, Applied Microeconomics, Public Management, Public Financial Management, and Politics and Process). IEM must be completed before you can enroll in your internship.
