Summary

iRead4Skills is a new web-based system designed for European Portuguese adult literacy programs, demonstrated at PROPOR 2026 in Salvador, Brazil. This system addresses the challenge educators face in finding and adapting short, reliable texts that match learners' reading abilities. iRead4Skills estimates text readability and complexity, aligning levels with the Common European Framework of Reference for Languages (CEFR). It identifies specific areas of complexity, such as lexical, grammatical, and semantic elements, and provides actionable, level-aware suggestions for rewriting. The system also includes curated lexical resources to aid in text adaptation, emphasizing transparency by showing users why a text is complex and how to revise it effectively without altering its original meaning.

Key takeaway

For adult literacy educators in Portuguese-speaking contexts, iRead4Skills offers a practical tool to streamline material selection and adaptation. You can use this system to quickly assess text complexity, understand the underlying reasons for difficulty, and receive concrete suggestions for revision. This will help you consistently provide appropriate, trustworthy reading materials tailored to your learners' specific CEFR-aligned reading abilities.
