Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s income tax provisions for all periods consist of federal, state and foreign income taxes. The income tax provisions for the three months ended March 31, 2020 and 2019 were based on estimated full-year effective tax rates, including the mix of income for the period between higher-taxed and lower-taxed jurisdictions, after giving effect to significant items related specifically to the interim periods, and loss-making entities for which it is not more likely than not that a tax benefit will be realized. The Company’s effective tax rate was approximately 2% and 4% for the three months ended March 31, 2020 and 2019, respectively. The Company’s tax benefit of $1.1 million for the three months ended March 31, 2020 related to losses generated by operations and the amortization of acquired intangibles in the Alternative Credential Segment that are expected to be realized through future reversing taxable temporary differences. The Company expects to continue to recognize a tax benefit in the future for the Alternative Credential Segment to the extent that this segment continues to generate pre-tax losses while carrying deferred tax liabilities that are in excess of deferred tax assets. To date, the Company has not been required to pay U.S. federal income taxes because of current and accumulated net operating losses.
