The errors spell-check misses

Spell-check catches "recieve". It does not catch "there section" or "the reports is ready", because every word is spelled correctly. Proofreading screenings are built from exactly these errors, so a candidate who relies on the red underline fails them.

The five families

1. Homophones. there/their/they're, your/you're, its/it's, to/too/two, past/passed. Read the sentence and ask which meaning fits.
2. Subject–verb agreement. "The list of items are" should be "is", because the subject is "list". Find the subject, then check the verb.
3. Missing or wrong word endings. "will takes", "are encourage", "any correction" (where plural is needed). These come from edits made in a hurry.
4. Possessives and plurals. "the customers account" needs an apostrophe; "the account's" as a plural does not.
5. Capitals and names. Days, months, places and product names. Easy marks if you look for them on purpose.

Read it twice, differently

First pass: read for meaning at normal speed and mark anything that makes you pause. Second pass: read one sentence at a time, backwards through the text, so the story cannot carry you past an error.

In a timed test

Most screenings give a passage of 150–300 words with 6–12 planted errors and a few minutes. Do not try to correct; just mark. Marking a correct word costs you (a false positive), so only flag what you can name: "this is a plural", "this is the wrong homophone".

Try the tap-the-errors test and read the explanation for each one you missed. After five attempts you will recognise the families on sight.
