Certified Quality Inspector Question Bank

Format Web-based

Simulate the CQI exam from the convenience of your home or office. Identify knowledge gaps and target your studies from test results. Review and reinforce your learning as part of your exam preparation.

Increase the effectiveness of your study for ASQ's Certified Quality Inspector (CQI) exam through access to hundreds of practice questions developed and based on the CQI Body of Knowledge (BoK)*. Use these questions to identify your strengths and weaknesses, so you know where to concentrate your studies.Study by topic or simulate the exam experience with at least three completely unique sets of questions drawn from the CQI BoK. Take a different random practice exam as many times as you want during the 365-day access period.*Please note that the questions in product are not actual ASQ exam questions. Your performance on the practice exams is for study purposes only, and may or may not reflect performance on an actual certification exam.

Please Note: ASQ is currently migrating this product to a new platform. When the migration (which will not include any new content) is complete, you will automatically receive it in your learning plan. You will have both versions in your learning plan until June 30, 2017. Access to the original version will no longer be available after 6/30/2017. Progress in the old version cannot be transferred into the new version. After June 30th, the old version will be removed from your learning plan unless completed. If completed, you will still be able to print your certificate of completion but will no longer be able to launch the old version.

We recognize this may be an inconvenience for you and we will be providing you with a full year (365 days) of access to the new course from the date you receive it (not your original purchase date). This applies only to purchases made after July 1, 2016.

WebEx – Virtual Course: Advance Preparation and Student Information

Join a Test Session

We strongly suggest that you join a WebEx test session in advance of your scheduled virtual training, using your preferred web browser. This can help prevent problems launching content the day your training begins.

If you do not have administrative privileges on the SAME computer you will be using the day of your training (i.e., your workstation within your organization) you may need the assistance of your local IT/IS help desk staff for the platform to engage correctly.

To join a test session (meeting), click here and enter your name and email address to join. If successful, you will see a screen that says "Congratulations! Your system is now set up properly ..."

Deactivate Pop-up Blockers

You should deactivate any pop-up blockers, spam filters, and company firewalls that could prevent the WebEx client platform or web-based course from working properly. Third-party toolbars such as Bing, Yahoo, and Google should also be disabled due to their own pop-up blocking capabilities.
