Spelling, punctuation and grammar (SPaG) is a discrete component of GL English and a contributor to extended writing marks in CSSE and ISEB.
What this question type tests
SPaG tests rule-based knowledge: capitalisation, full-stop and comma use, apostrophes (contractions and possession), direct speech punctuation, and basic sentence types.
How it appears in real papers
In GL English papers, SPaG accounts for 15 to 25 percent of marks across spelling, punctuation and grammar sub-sections. Recognising the question type within five seconds is the marker of a confident candidate; recognising it after thirty seconds of re-reading typically means a lost mark on a tight paper.
The technique to learn
The technique: rule-by-rule mastery rather than reading-by-osmosis. Learn one apostrophe rule per week — its/it's, possessive nouns, plural possessives — and drill until automatic.
For spelling, focus on rule patterns (i before e, doubling consonants, dropping silent e) rather than memorising lists. Pattern-knowledge transfers; list-memorisation does not.
Worked example
Worked example: "the dogs bone" — needs an apostrophe for possession. Singular dog: "the dog's bone". Plural dogs: "the dogs' bone". Children mix up these two routinely. Drill the distinction with 20 examples.
Common errors
Common error: treating SPaG as a comprehension by-product rather than a discrete subject. SPaG marks come from rule-based answers; reading widely helps less than focused rule drilling here.
Practice approach
Use a SPaG-specific workbook (CGP's SPaG range is the standard) for 15 minutes three times a week. The marks compound — every well-learned rule recurs in multiple papers. Embedding the technique requires repeated exposure across different surface presentations — a child who has only seen one phrasing will be thrown by the next.
