Supporting research in English language testing

We are conducting research, using independent researchers, to inform the development and validation of PTE Academic. A Technical Advisory Group, comprising experts from both language testing and psychometrics, also provides feedback, advice and critical assessment.

Our in-house research includes:

  • Developing item writer guidelines derived from the CEFR

  • Relating item difficulty and lexical cohesion

  • The Pearson International Corpus of International English (PICAE)

  • Developing marking criteria based on the CEFR

  • Investigating the effect of partner scores in paired oral assessment

  • Assessing academic English listening

  • Concordance studies (relating PTE Academic scores to predictions of scores on other high stakes tests)

Automated scoring

PTE Academic tests are scored using our extensively tested automated scoring technologies, trained on sample marks from more than 10,000 students with 126 native languages.

The result is highly accurate, objective, and consistent scoring for every test taker.
