After discussing what pay is like for crew chiefs/senior techs it would be good to mention what it takes to get such a job. For this I used the the requirements listed in job postings same as I used for pay rates. As with field techs there is over lap so some categories do not add up to 100% e.g. some posts said a MA preferred but BA acceptable in which case both were marked down as both could get someone a job. The results were:
I left the graph as practically indistinguishable to illustrate that point that because the crew chief/senior tech. position is sort of an in-between position, not every company has such a position, there is a very mixed bag in what skills are required. What stands out though is the need to at least have a BA and a MA would not hurt. After that regional/local experience is the next most important asset to have. Everything else tends to fall under 25% though having 5 years of experience would qualify or over qualify a person for 80%+ of jobs while 1 year of experience in archaeology would only qualify one for 35% of jobs.
