The CSI CSA objectives for computer literacy are aligned with IC3 Internet and Computing Core Certification.
There are many resources for those wishing to study on their own.
Since the CSA is aligned to IC3, any IC3 training materials, books, or websites will assist in learning the required knowledge and skills.
And for current CSI students the CSI Learning Express Library offers short computer skills training courses for several different applications. http://www.learnatest.com/LEL/index.cfm/learningCenter/computerSkills
