The net loss for 2020 of $72.0 million, a decrease from net earnings of $112.4 million in 2019, was due primarily to lower earnings from operations due to the goodwill impairment charge taken in the first quarter of 2020, combined with losses of Persol Holdings common stock, partially offset by the impact of an income tax benefit in comparison to income tax expense in 2019. 25 Operating Results By Segment (Dollars in millions) 2021 vs. 2020 2020 vs. 2019 2021 (52 Weeks) 2020 (53 Weeks) % Change 2020 (53 Weeks) 2019 (52 Weeks) % Change Revenue From Services: Professional & Industrial $ 1,837.4 $ 1,858.4 (1.1) % $ 1,858.4 $ 2,213.4 (16.0) % Science, Engineering & Technology 1,156.8 1,019.1 13.5 1,019.1 1,131.8 (9.9) Education 416.5 286.9 45.2 286.9 450.7 (36.3) Outsourcing & Consulting 432.1 363.5 18.9 363.5 377.7 (3.8) International 1,067.8 988.6 8.0 988.6 1,182.5 (16.4) Less: Intersegment revenue (0.9) (0.5) 97.0 (0.5) (0.5) (16.6) Consolidated Total $ 4,909.7 $ 4,516.0 8.7 % $ 4,516.0 $ 5,355.6 (15.7) % 2021 vs. 2020 Professional & Industrial revenue from services decreased 1.1% due primarily to lower demand from our outcome-based call center specialty.

Therefore, we performed an interim step one quantitative test for our previous reporting units with goodwill, Americas Staffing and GTS, and determined that the estimated fair values of both reporting units no longer exceeded their carrying values.
These changes in market conditions caused another triggering event requiring an interim impairment test for goodwill as of year-end 2022. We performed an interim step one quantitative test for RocketPower’s goodwill and determined that the estimated fair value of the reporting unit no longer exceeded the carrying value as of third quarter-end and year-end 2022.
This was partially offset by earnings from Softworld, which was acquired in April 2021. Education reported earnings of $3.0 million, compared to a loss of $9.0 million from 2020. The change was primarily due to an increase in revenue, reflecting the return to in-school instruction by many schools, resulting in increased demand for our services as compared to 2020.

Income tax benefit was $34.0 million and expense was $0.4 million for 2020 and 2019, respectively.

Income tax benefit was $7.9 million for 2022 and income tax expense was $35.1 million for 2021. 2022 benefited from lower pretax earnings, changes in the fair value of the Company’s investment in Persol Holdings, and the impairment of tax deductible goodwill. These benefits were offset by the charge associated with tax exempt life insurance cash surrender value losses.
On an organic basis, revenue growth was 3.9%, which was driven by hours increases in our staffing business across most specialties, coupled with an increase in outcome-based revenue and permanent placement income. The 53rd week added approximately 1% to 2020 reported revenue from services in Science, Engineering & Technology.
Excluding the impact of the addition of Softworld revenue in the first quarter of 2022, the revenue growth was 6.1%, which was driven by increases in our outcome-based services as well as an increase in revenue in our staffing business coming from increases in bill rates and permanent placement income, partially offset by a decline in hours.
In the fourth quarter of 2020, the Company elected to perform a step zero qualitative analysis to determine whether a further quantitative assessment was necessary for the reporting unit with goodwill.
Additionally, we performed a step zero qualitative analysis for the Education and RocketPower reporting units to determine whether a further quantitative analysis was necessary and concluded that a step one quantitative analysis was not necessary at that time.
The Outsourcing & Consulting gross profit rate increased 60 basis points due to improved customer mix in the RPO product, coupled with lower employee-related costs in the PPO product. International gross profit declined as a result of lower revenue volume and a decline in the gross profit rate.
