Testing Policies and Procedures
A candidate will receive written acknowledgement of receipt of application from the testing office at Credentialing Services (CS), Inc. Eligible candidates will be sent an admission ticket prior to the test date. Candidates who do not have an admission ticket one (1) week prior to the test date should call CS at (309) 343-1202 for instructions.
Candidates who cannot sit for the examination should notify CS in writing prior to the day of the test. Emergencies that prevent a candidate from appearing on the day of the test must be reported and explained in writing within fifteen (15) days of the test date. Candidates whose eligibility is in question will be asked for more information and/or documentation.

Test Date

The test date and times will be announced as they are determined by ISWM.

Admission to Testing

Each candidate must present an admissions ticket and two (2) forms of identification to be admitted to the testing area. One of the forms of identification must include a photograph. In case of a lost admission ticket, call CS at (309) 343-1202 for alternate authorization to sit for the examination.

Test Center Regulations

The following regulations will be observed at all test sites to insure uniform testing conditions:
  1. Arrive at the test site on time. Proctors will not admit candidates who arrive after the reading of examination instructions has begun.
  2. Bring several sharpened #2 pencils.
  3. Non-programmable, silent calculators may be used only if they do not require electrical outlets.
  4. Visitors are not permitted.
  5. Proctors are instructed to answer questions about the testing procedures only. They will not respond to inquiries regarding examination content.
  6. No reference materials of any kind are permitted.
  7. No memoranda, documents or test materials of any sort may betaken from the test site.

Pass/Fail Standard

The passing level is a standard of knowledge set by a criterion referenced methodology (similar to setting par in golf), using the combined judgments of the Examination Committee resulting in a recommendation to the Certification Committee for final review. Using this methodology there is no curve, and candidates do not compete against each other.

ADA Compliance

Test locations are accessible. Applicants should advise ISWM staff of their requirements in writing no later than the deadline for application.

Test Results

Candidates will be mailed written notice of their examination results approximately six (6) to eight (8) weeks after administration or portfolio submission.

Retake Examinations

Unsuccessful candidates may retake the examination or portfolio analysis twice without paying additional application fees. Test fees do apply to each attempt, however. If a candidate fails three times, the candidate must reapply, paying the application fee again.

Certification Renewal

Renewal of certification will be required after five (5) years. Renewal can be achieved through ISWM authorized continuing education programs or a retaking of the certification examination or portfolio analysis, depending on ISWM’s policy at the time.

Security and Revocation of Certification

Anyone giving or receiving assistance of any kind from another person during the test will be required to turn in his/her test materials immediately and leave the test site. The candidate’s answer sheet will not be scored and application and testing fees will not be refunded. Any candidate who either removes or attempts to remove test material from the test site may be prosecuted and forfeits all rights to sit for the exam again. The application and test fees will not be refunded. In addition, candidate risks revocation of previous ISWM Certifications for these actions.
ISWM reserves the right to refuse or revoke any certification in the event the recipient has been found to be acting in a deceptive or unethical manner of any kind. There is a review process for any candidate whose certification has been revoked. Candidates who desire to appeal must do so in writing to Credentialing Services, Inc. within 45 days of the revocation. For more information on the appeals process, contact Credentialing Services.
