. Information and communication technologies (ICT) are a set of equipment (devices, systems, etc.) and techniques with associated software (software systems and software tools) that have been developed and used for more efficient communication, creation, distribution, storage and management of information. The IDI (ICT Development Index) index is most often used to measure ICT resources, which is defined as a composite index that combines 11 indicators (classified into 3 sub-indices: Access, Use and Skills). Data on values of IDI index has been retrieved from Measuring the Information Society Report (MISR), which since 2008 has been publishing by International Telecommunications Union (ITU). The IDI index for 2017 was determined for 176 countries of the world, with the first on the ranking list was Iceland with IDI2017=8.98 and the last Eritrea with IDI2017=0.96. The mean value of IDI index for 2017 was Avg=5.11, standard deviation was StD=2.22 and coefficient of variation was CoV=43.52. In this paper is given of analysis of IDI (ICT development index) for measuring ICT resources in Georgia. The data were approximated using a 3rd degree polynomial regression model (PRM3) with a correlation coefficient R=0.9964, determination coefficient R2=0.9928 and adjustment coefficient of determination is AdjR2=0.9885.
