I've just sent a letter to a school in a West African country that has had and continues to have serious political problems and violence. My reasons for wanting to take a position at the school are as much about the school as my passion for the history of the country and the region in general. I feel, wanting to be succinct in my cover letter and CV, that I did not express this passion and that it may benefit me in the application process as I'm sure they are looking for people who know what they are getting into. I'm tempted to follow up my CV and cover letter with a 'letter of motivation' outlining my passion for the politics of the region and my wish to teach the future leaders of the country. How would this be seen by the administration? My feeling is it couldn't hurt..
