Who I am & why ESL Materials exists
My name is Thomas Gueguen, and I am a CELTA-certified ESL teacher. Since earning my CELTA from Cambridge in 2018, I have taught in adult education programs in France, corporate training groups (including Bouygues and Veolia), and one-to-one settings online.
I founded ESL Materials because teachers waste countless hours filter-searching worksheets and platforms. We do not need another directory containing thousands of worksheets; we need a curated, tested shortlist of materials that respect both a teacher's schedule and a student's intelligence.
My curation & testing protocol
How every recommended tool or platform on ESL Materials is audited before being published:
- Personal investment — I pay for premium tiers with my own money to test features, templates, and onboarding from a regular teacher's perspective.
- Content sampling — I audit representative curriculum guides or worksheets across diverse levels to evaluate depth and format variety.
- Real-world classroom run — I teach using the resources in my own courses, tracking engagement, lesson rhythm, and student feedback.
- Multi-week durability — A resource package is reviewed over two weeks of lessons to ensure it holds value beyond a single novelty class.
- Comparative review — I measure the platform against free and premium alternatives to verify if the pricing structure is justified.
- Quarterly audits — If platforms change their pricing tiers, features, or interface layouts, reviews are updated.
What I refuse to recommend
Trust is built on filters. I deliberately exclude the following from this site:
- AI-generated worksheet mills — Low-quality sheets that teach incorrect English syntax, have no editorial oversight, and lack classroom validation.
- Template cloaking packages — Collections promising 5,000+ files that are just subtle copy-paste variations of the same basic worksheets.
- Account friction blocks — Worksheets that force students to set up accounts just to complete a routine reading list.
- Editorial bias — Affiliate sponsorships that override my honest classroom reviews. If a paid platform degrades its product, I remove it.
Teaching contexts
- Adult immigrant programs — Southwestern France (Béarn), supporting learners preparing for A1 to B1 integrations.
- Corporate workshops — English language training programs for teams at corporate firms including Bouygues and Veolia.
- Digital one-on-one — Online adult tutoring for European and North American professionals (Preply and italki).
- Community seminars — TOEIC prep and adult community courses at the local English Workshop in Oloron.
My teaching philosophy
Worksheets are confidence-building devices, not just paper tasks. A well-designed resource gives learners dignity, clarity, and safety to try, fail, and improve.
I do not believe in shortcuts to fluency, but I do believe in kinder pathways. The best resources empower teachers to build authentic, communicative environments in their classrooms.
What I do on this hub
- Curate resources — Filtering high-value sheets, lesson packs, books, and software so teachers save time.
- Write practical guides — Actionable classroom strategies focused on speaking anxiety, adult learning dynamics, and pair work.
- Build free tools — Providing accessible open resource directories for independent teachers without budgets.
- Stay current — Auditing modern tools, learning dashboards, and AI writing assistants for class readiness.
