Lecturer
- Fernando Manuel Conceição Costa

Prerequisites
Not applicable.

Objectives
1. Develop the ability to observe the work of art, necessary to analyze and prepare diagnoses prior to the intervention;
2. Develop the capacity for graphic, photographic and bibliographic research, as well as complementary means of investigation to support the intervention;
3. Develop the ability to summarize the documentation created during the work through the preparation of a final report similar to the reports required by Decree-Law 140 of 2009;
4. Develop the technical skills necessary to work in the context of conservation and restoration work, applying the acquired knowledge in practice.

Practice Component

1. Application of the concepts learned in the Theoretical Component in the context of the work.
2. Creation of a technical report similar to the reports performed in conservation and restoration companies.

Evaluation Methodology
Completion of the Practice component with an achievement equal to or greater than ten values is mandatory in all evaluation periods.

Evaluation in frequency season.
Practical part (practical performance 20% + technical report 40%) and Theoretical part (Frequency 40%). The student is exempt from the exam whenever he/she completes each of the components with a grade equal to or greater than ten values.

Assessment in exam season or special season/student worker
Practical part (practical performance 20% + technical report 40%) and Theoretical part (Exam/Special/Student Worker 40%). The exam grade and the final average must be equal to or greater than ten values.

Method of interaction
Theoretical Lectures and laboratory classes where students are asked to run diagnostics, methodologies and also conservation and restoration interventions in real context.
