Teaching methods

Theoretical lectures and laboratory exercises

Assessment methods

The verification of learning tends to ascertain the achievement of the educational objectives of teaching, i.e.:

- the ability to apply acquired theoretical and practical knowledge to food quality analysis and control;

- the ability to interpret and apply analytical methods, even instrumental ones, useful to the dosage of food.

The test is carried out with the conduct of a practical laboratory test, carried out at the end of the single-seat exercises, and final oral examination. The practical test, with unlimited validity, is preparatory to the oral examination.

Students, to whom the Council validates the signature of attendance acquired in the previous career, must pass the laboratory practice test before taking the oral test.
