    Possessive determiner must agree in number: use “unsere”.

  • Alle unsere Trainer ist komplett zertifiziert.

    Verb must agree with the plural subject “Trainer”.

  • Alle unsere Trainer sind komplett zertifiziertes.

    When used predicatively after “sein”, the participle stays uninflected; don’t add an ending.

↔Alternatives

Cultural Tip

In German business communication, “komplett zertifiziert” sounds strong and confident, but “vollständig zertifiziert” is a slightly more formal alternative. Avoid mixing singular and plural forms – the verb must match the plural noun “Trainer”. Also, German speakers appreciate precise wording, so stating the exact type of certification (e.g., “nach DIN‑EN‑ISO‑9001 zertifiziert”) can add extra credibility.
