Vocabulary (Lexical Resource) for the IELTS Exam — Brazilian candidates

15% of the IELTS test plan. Lexical Resource is one of four scored criteria across Writing and Speaking — assessing range, accuracy, collocation, and idiomatic flexibility. Calibrated for Brazilian candidates.

High-stakes exams reward two skills equally: knowledge and test-craft. This page focuses on both for one of the most failure-prone areas. Vocabulary (Lexical Resource) sits at roughly 15% of the International English Language Testing System content distribution — Vocabulary is half of the Lexical Resource score. Band 7+ requires 1,500+ active topic-relevant words across academic, abstract, and discussion contexts. Pass rates for the IELTS are published annually by the awarding body and vary by cohort and locale. For Brazilian candidates preparing for IELTS, the calibration of study to local context matters: ENEM is Brazil's national entrance exam. For international study, IELTS and TOEFL dominate; CDL US licensure is a growing cross-border opportunity.

Pass rates for IELTS (Brazil) are published periodically by the awarding body.

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

  • !Repeating high-frequency verbs (good, big, important)
  • !Wrong collocations ("make a research" instead of "do research")
  • !Over-formal or over-academic vocabulary in Speaking
  • !Vague abstractions where specific examples are stronger

Study tips

  • 1Build word families: 5 derived forms per topic word (analyse/analysis/analyst/analytical/analytically).
  • 2Drill 20 academic collocations per day.
  • 3Practice replacing 5 high-frequency words per essay (good → beneficial; big → significant; important → crucial).
  • 4Read journal articles in your target field — academic vocabulary in context.
  • 5Brazilian candidates preparing for IELTS should account for visa-processing timelines if testing abroad — most U.S. test centres require a B1/B2 visa appointment scheduled 90+ days in advance.

  1. 1

    In IELTS Writing, "An overview of the data shows that the trend is good" — which is the strongest band-7 rewrite?

    • AThe data shows good trends.
    • BAn overview reveals a generally favourable trend across the period.Correct
    • CThe data is good and shows the trend.
    • DIt can be seen that the trend was good.
    Why this answer?

    "Reveals a generally favourable trend" replaces the weak verbs "shows" and "is", upgrades "good" to "favourable", and adds the precise scope ("across the period"). Each upgrade is a Lexical-Resource gain.
