For SLATE, the Reading, Listening, and Grammar sections are scored automatically by the computer. For the additional two sections in the SLATE-Plus exam, the Writing and Speaking samples are evaluated by native English speaking ESL trained professionals, according to a standardized scoring rubric.
Each test section is weighed equally. There is no penalty in the multiple-choice sections for guessing/incorrect answers.
The SLATE Official Score Report presents an individual's scoring information in both tabular and graphical formats. The graphical format, referred to as the Skill Profile, is particularly useful for displaying an examinee's strengths and weaknesses in each of the three or five areas tested.
