Since 2003, almost every public institution has developed a web site through etransformation project (eDTr) in Turkey. When there are so many institutions and different web sites, a need for standard becomes inevitable. To address this need, a standard was published by T&Uuml / RKSAT A.S. in January 2009 which constitutes of the rules and recommendations for these web sites referencing international web standards as well. The purpose of this study is to analyze the compatibility of public institutions&rsquo / web sites in Turkey with the T&Uuml / RKSAT standard. In this study, 32 rules are selected to be verified for 50 public institution web sites. 20 of the rules are verified with a tool named WSSCV which is developed in the context of this thesis, 5 of the rules are verified with a commercial tool named Total Validator, and 7 of the rules are verified manually. Results show that, the standard prepared by T&Uuml / RKSAT is not used during the development of a public institution web application. Compliance of the checked web sites to the standard is very low. However, the standard also needs to be updated according to today&rsquo / s technology.
