Prerequisites and restrictions
An MA thesis can consist of a study of material culture, a study based on fieldwork or laboratory research, or a literature study. However, in all cases, it will not suffice to give a description of the data studied. The student will have to show that he/she realises how the research is positioned in a broader field, what the taphonomic and methodical problems are which may perhaps be attached to the research, and will have to go into the theoretical and/or methodical perspectives that can be linked to the research problem.
The thesis should contain 20,000-30,000 words, figures, tables and a reference list (40-60 pages in total, appendices not included). The length of the thesis is not a norm in itself. A high quality thesis can be short; a sizable thesis is not a guarantee for success.
More information on writing your thesis, forms and criteria is on the archaeology website: http://archaeology.leiden.edu/graduate-school/masterprogramme/standards-procedures/r-mathesis.html
