The Witness Fitness Centre is an accounting simulation produced by the Certified General Accountants of Canada. The resource package is known as the School Accounting Modules and is distributed free (one copy per school) by the provincial associations of the CGA .

Although Pearson Education has no involvement in publishing the School Accounting Modules (SAM), one of the authors of ACCOUNTING 1, Tim Ireland, wrote the four editions of SAM.

The new revision of SAM was released in May 2005. It includes updated instructions for Simply Accounting 2004 and QuickBooks 2005. The core of SAM—the source documents—are viturally the same as they were in previous editions.

The 2005 version of SAM is now being distributed by provincial CGA organizations as pdfs via their websites. Visit cga-online.org to discover the address of your local CGA association.
