The TOEFL test is scored using both automated computer scoring and human raters (highly trained professionals) to ensure unbiased and accurate results for all four TOEFL test sections.
And only the TOEFL test uses a network of multiple, rigorously-trained human raters to score the test anonymously, using a quality-control process that meets the highest standards of fairness and objectivity. No other English-language test uses these methods, which can prevent inconsistencies in scoring.
Why is this an advantage for you? It means your score is an accurate, comprehensive and trusted assessment of your English skills — for you and the universities considering you for admission.
