International Society of Parametric Analysts

A Professional Society Devoted To:

ISPA Website

ISPA is a professional society dedicated to the improvement and promotion of parametric cost modeling techniques and methodologies and the related fields of risk analysis, econometrics, design-to-cost, technology forecasting, and management. ISPA provides a forum that encourages the professional development of its members through the interchange of ideas and perspectives.

ISPA members represent government agencies, universities, and nearly 200 organizations in 12 countries. ISPA’s membership range in experience from beginners to seasoned professionals. They are united by their interest in the practical application of parametric analysis

Parametric Analysis

Parametric analysis employs equations that describe relationships between cost, schedule, and measurable attributes of systems, hardware, and software. The equations describe how a products physical, performance, and programmatic characteristics affect its cost and schedule.

Parametric techniques have proven their ability to extrapolate from past and current experience to forecast the economic impact of fast-developing technologies. These techniques are applied using custom cost estimating relationships or commercially available tools.

Society Activities

Mission Statement

The purpose of ISPA is to improve our effectiveness and leverage the limited resources of our respective organizations by providing information on techniques, tools, and methodologies for enhancing the management decision-making process.

Organization Profile

In 1978, a small dedicated group of cost analysts and estimators saw the need for an organization that would support their development in a new discipline called Parametrics. ISPA’s long history of growth and professional excellence is a tribute to their pioneering vision. ISPA is chartered in Washington, DC., as a nonprofit educational society. Many ISPA members are currently participating in the Parametric Estimating Initiative which is enabling them to rely on Parametrics as the primary basis of estimate.

ISPA members represent government agencies, universities, and nearly 200 organizations in 12 countries. ISPA’s membership range in experience from beginners to seasoned professionals. They are united by their interest in the practical application of parametric analysis

ISPA has chartered regional Chapters for technical workshops, training, and networking opportunities to meet and associate with others in our profession. ISPA has also collected a library of over 800 publications which has been especially helpful to many new member


The Journal of Parametrics is a semi-annual professional publication. Parametric World is the quarterly newsletter of the International Society of Parametric Analysts. To view examples of these publications, click on the references below.

International Annual Conference

The highlight of the year is the International Conference held in a variety of geographic locations to meet the needs of our international membership.

The purpose of this annual meeting is to give members the opportunity to exchange ideas and enable developers of parametric techniques and models to show their accomplishments. Tutorials and special workshops are conducted that feature presentations on modern techniques for analyzing and estimating cost, schedule, and the impact of new technologies. Many vendors of parametric models, software tools, and services are exhibited.

Parametric Practitioner Certification Program

ISPA is pleased to announce a new professional advancement and development program. The successful applicant upon completion of an examination at the 2002 Annual Conference in San Diego, will be granted the award of Certified Parametric Practitioner (CPP). This program is conducted by ISPA for both members and nonmembers. It provides professional recognition to those applicants possessing the requisite education and job experience and who successfully demonstrate their knowledge and skills through a written examination.

Procedures to Apply for the Certification Examination

Upon determination by an applicant that they are eligible (see eligibility requirements below), the applicant must complete the "Application for Certification Examination" form and mail it to:

ISPA CPP Program
Fred Tucker
P.O. Box 9699
Canoga Park, CA 91309

The application form can be obtained by clicking here: Certification Form. Download a copy of the form in Word format to your computer, fill it out and mail back to us at the address above or contact the business office. The fee for the examination is $75.00 payable at the time the completed application is submitted. Of this amount $60.00 is refundable should an applicant withdraw prior to the date of the exam, fail to take the exam, or fail to meet the eligibility requirements to take the test as determined by the Society Certification Committee.

Examination Details

Certification Committee Review. The Certification Committee will determine whether an applicant qualifies under one of the options listed below. The decision by the Committee will be final. The applicant’s fee will be refunded minus a $15.00 administrative charge if he or she is found not qualified to take the test. An applicant may resubmit their application at any time with additional information for reconsideration. The fee for first-time resubmission is $65.00.

Examination Schedule. The certification examination will be administered each year at the ISPA Annual Conference. Upon acceptance of the application by the Certification Committee, an applicant will be notified of eligibility and of administrative matters, including location, time, and points of contact. The qualified applicant may sit for the examination without attendance at the annual Conference. Attendance at the annual Conference is encouraged.

Notification of Examination Results. Within sixty days after an applicant takes the examination, they will be notified of the results in writing. Successful applicants will be issued certificates showing successful completion. Unsuccessful applicants may retake the examination two additional times for a reduced fee of $65.00 for each test. After two failures, a candidate must apply again and retake the exam for the standard fee of $75.00.

Eligibility to Take Written Examination

Each applicant applying for certification must qualify with one of the three following eligibility options:

Option A. A college degree in a field of study directly related to parametric analysis and estimating or, if the degree is not related, then a minimum of ten college level courses related to estimating. Some examples of these courses are (but are not limited to) statistics, advanced statistics, parametrics, calculus, and software cost estimation. Additionally, a minimum of two years experience performing parametric analysis and estimating activities in a position specifically identified within the applicant's organizational structure as requiring such performance is required. The position must, in the judgment of ISPA’s Certification Committee, involve parametric estimating or analysis duties normally performed by a fully qualified analyst or estimator.

Option B. An associate college degree and five years experience in performing parametric estimating and analysis activities in a position as defined under Option A.

Option C. A minimum of seven years experience in performing parametric estimating or analysis activities in a position as defined under Option A. Also, the demonstration of an applicant's ability or knowledge to pass the examination through submission of a brief biographical sketch describing education, experience, and most recent relevant estimating or analysis performance is required.

Eligibility questions should be referred to the Certification Committee in writing.

Recertification Program

The Certified Parametric Practitioner (CPP) award is valid for five years. The Recertification Program will permit the continued certification of practitioners. Recertification may be achieved by successfully passing the regular CPP examination. If a certified member wishes to achieve recertification by examination the procedures described above for initial certification apply, except that the member is automatically eligible to take the examination regardless of education and experience requirements that apply for candidates who wish to take the examination for the first time. The same examination will be taken for either certification or recertification. You may request Recertification during the period six months before to six months after the fifth year anniversary of the last certification.

Please contact Douglas Druley with any questions/comments related to the CPP program.
