Improvement of quality of public services is one of the important goals in the advancement of the operation of state / public administration in Latvia. The aim of the research was to evaluate the quality of customer service in the institutions of public administration in Latvia, to perform the factor analysis of the collected data.The research was based on the selection of customers of public services, in total of 292 people in Riga and in Latvian regional centres in 2017-2018. The research was conducted in public institutions of Latvian regions that provide social assistance (SSIA – the State Social Insurance Agency), offer employment promotion services (SEA – the State Employment Agency); realize tax policy in the state (SRS – the State Revenue Service), implement the state environmental protection policy (MEPRD – Ministry of Environment Protection and Regional Development); provide legal aid services (DC – Daugavpils Court). The quality of services provided to the clients of corresponding institutions was evaluated. For the data collection, the service quality assessment model – the SERVQUAL instrument (Parasuraman et al., 1988) was used, as well as the analysis of the research data factors was carried out.The service quality assessment revealed that the performance of public service organizations in Latvia does not meet the customers’ expectations. The evaluation of service quality provided by public authorities, as well as their regular monitoring would improve the quality of services provided.

At present, the service sector receives growing attention taking into account its role in the socio-economic development of the society. Public services produced to meet the demands of the population occupy a special place in this sphere. Improving the quality of public services is one of the essential goals in improving the functioning of public administration in Latvia and globally. The research aimed to assess the customer service quality of administrative services provided by Latvia's public administration institutions, performing the factor and cluster analysis of the collected data. Research base: Public administration institutions (6) and their branches (17) in Latvia. The research participants are two hundred ninety-two occasionally selected customers of public administration institutions who filled in SERVQUAL questionnaires before and after their visit to an institution. The sample of customers is occasional and administratively territorial, observing the proportional representation of planning regions. The service quality assessment modelthe SERVQUAL instrument (Parasuraman et al., 1988), was used for the data collection. The analysis of the research data factors and clusters was carried out. Service provision quality in all quality dimensions has been given a negative evaluation. The economic efficiency of the largest state institutions understudy is low, and so is the quality of provided services as evaluated by their customers.
