In this chapter, the authors try to stand out how the Latin American governments, specifically the Peruvian government, can evaluate its efforts implementing electronic administration initiatives, identifying what the citizen expects from the electronic administration and how he or she perceives it, applying an evaluation model to the electronic tax payment service implemented, as a successful initiative at Latin-America. The proposed model to achieve this, was developed by one of the authors during his doctoral dissertation (Cardona, 2004) and evaluated by the other one as dissertation judge. It includes five different independent and latent constructs, Attitude, Aptitude, Trust, Relevance and Satisfaction that affect two dependent and latent constructs, the Citizen Perception and the Citizen Expectative towards its relationship with the Public Administration through the use of Information and Communication Technologies - ICT, under the effect of illustrative variables related with citizen, institutions and context.
