Abstract:
Banking sector and its performance play an important role in an economy. The banking 
industry in Ethiopia is now booming due to the financial liberalization and restructuring 
of financial institutions.  Currently, there are a total of 30 licensed banks that are giving 
financial services consisting of 8,250 branches, serving the country’s population of 
nearly 115 million.  The current scenario of Ethiopian banking sector is very dynamic 
and competitive. To maintain market share it is necessary for banking institutions to 
acquire large customer base by differentiating their service quality provision through 
implementing different strategies. Customers today are very much aware about various 
financial services and institutions; they can only be retained by providing good quality 
services. Therefore, this study aimed to assess and compare the similarities and 
differences of private and public banks service quality provision as perceived by 
customers in terms of the tangibility, reliability, responsiveness, assurance and empathy 
service quality dimensions.  Cross sectional data were collected through close ended 
questionnaires which incorporate demographic and service quality measurement 
dimensions adopted from SERQUAL model. The researcher was used descriptive 
research design and a sample of 383 respondents was taken by following Krejcie and 
Morgan formula. Five commercial banks (Commercial Bank of Ethiopia, Cooperative 
Bank of Oromia, Awash Bank, OromiaBank and Dashen Bank) that found in Holeta town 
were selected purposively based on their higher number of customers they hold. The 
collected data were analyzed using descriptive and inferential statistical tools like 
frequency, mean, one sample t-test with the help of SPSS version 20. Cronbach’s alpha 
test is used to analyze reliability of the variables.  Pearson correlation was applied to 
determine the relationship between service quality dimensions and customer satisfaction. 
To measure the gap between the customers’ expectations and their perceptions, 
Parasuraman SERVQUAL Model was used. The results of the study revealed that service 
gap is higher in private sector banks than public sector bank which indicates that the 
public sectors bank customer were highly satisfied when compared with private sectors 
bank customers. In all the SERVQUAL dimensions the customers’ perceptions are lower 
than their expectations. Therefore, both the type of banks must increase their quality 
service to minimize the existing service gaps and improve their customers’ satisfaction. 
Specifically, the private banks should have a strong customer relationship management 
and be able to understand the customers’ needs while interacting with them
