Test Your Error Detection
For Online Jobs
Five detection exercises from basic spelling to full editorial review.
Each format matches what employers test when screening for content QA, editorial, and proofreading roles.
Grammar Errors
Find subject-verb disagreements, tense shifts, and structural grammar issues in professional text.
Spelling Errors
Spot misspellings and transpositions — the most basic proofreading skill employers test.
Punctuation
Find missing commas, incorrect apostrophes, and semicolon misuse in formal documents.
Factual Errors
Identify factual inconsistencies and logical errors — numbers, dates, and claims that don't add up.
Full Edit Mode
Complete editorial review — grammar, spelling, punctuation, and style all at once.
About Proofreading Practice
Proofreading roles require detecting errors that automated spell-checkers miss — contextual grammar mistakes, punctuation inconsistencies, factual errors, and style issues. Employers commonly screen candidates with a timed passage containing deliberate errors. Your detection rate (percentage of errors found) is the primary metric. HomebaseWorks offers five proofreading formats with different error types. All tests are free.
HomebaseWorks is an independent skill practice platform. Practice scores are self-assessment indicators — not employer-verified credentials. Always verify requirements directly with employers. Never pay any fee to apply for a job.
