Finnish to English Other Education / Pedagogy

Coud anyone help me with the meaning of suoritus here in this context, please? Could that be performance discourse or execution discourse, in a practical (non-empirical) sense?
Please find below my translation for the sentence, if there are any other ideas, they'd be more than welcome! :-) Thank you once again...

"Asiantuntijadiskurssi muodostui suoritusdiskurssille alisteiseksi, puheessa vähempiarvoiseksi ja väistyväksi diskurssiksi, johon vedottiin useimmiten vasta silloin, kun opettajat kokivat joutuvansa oikeuttamaan ja perustelemaan omaa vallankäyttöään."

"For the performance discourse, the expert discourse came across as a subordinate, speech-underrated and evading discourse, which it has been for the most part invoked only when teachers found themselves having to legitimise and justify the use of their own authority"
