The fiscal year change was effective beginning with the 2011 fiscal year, which began January 2, 2011 and ended December 31, 2011. As a result of the change, the Company had a five-week transition period which began November 28, 2010 and ended January 1, 2011 ("transition period"). The audited results of the five-week transition period are presented herein. The fiscal year change was not effective until after the completion of the 2010 fiscal year. Therefore, the fiscal year 2010 comparative financial and other information reported in the financial statements herein continues to be presented based on the Company's prior fiscal year end calendar.</font></p> <p style="FONT-FAMILY: times"><font size="2">        CRA's fiscal years periodically contain 53 weeks rather than 52 weeks. Fiscal 2012, 2011, and fiscal 2010 were 52-week years.</font></p></div>
CY2012	us-gaap	Use Of Estimates UseOfEstimates	<div style='font-size:10.0pt;FONT-FAMILY: Times New Roman;'> <p style="FONT-FAMILY: times"><font size="2"><b><i>Estimates</i></b></font></p> <p style="FONT-FAMILY: times"><font size="2">        The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make significant estimates and judgments that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements, and the reported amounts of consolidated revenues and expenses during the reporting period. Estimates in these consolidated financial statements include, but are not limited to, accounts and unbilled receivable allowances, revenue recognition on fixed price contracts, depreciation of property and equipment, share-based compensation, valuation of acquired intangible assets, impairment of long lived assets, goodwill, accrued and deferred income taxes, valuation allowances on deferred tax assets, accrued compensation, accrued exit costs, and other accrued expenses. These items are monitored and analyzed by the Company for changes in facts and circumstances, and material changes in these estimates could occur in the future. Changes in estimates are recorded in the period in which they become known. CRA bases its estimates on historical experience and various other assumptions that CRA believes to be reasonable under the circumstances. Actual results may differ from those estimates if CRA's assumptions based on past experience or other assumptions do not turn out to be substantially accurate.</font></p></div>

The Company performs a credit evaluation of its clients to minimize its collectability risk. Periodically, the Company will require advance payment from certain clients. However, the Company does not require collateral or other security. The Company maintains accounts receivable allowances for estimated losses and disputed amounts resulting from clients' failures to make required payments. The Company bases its estimates on historical collection experience, current trends, and credit policy. In determining these estimates, CRA examines historical write-offs of its receivables and reviews client accounts to identify any specific customer collection issues. If the financial condition of any of CRA's customers were to deteriorate, resulting in an impairment of their ability or intent to make payment, additional allowances may be required.</font></p> <p style="FONT-FAMILY: times"><font size="2">        A rollforward of the accounts receivable allowances is as follows (in thousands):</font></p> <div style="PADDING-RIGHT: 0pt;
