To collect the data, the researcher did online with the non-certified English teachers at SMP IT Nur Syamzam Kolaka. Using Pearson's correlation coefficient, the relationship between the application of TPACK and the availability of ICT tools was determined by correlating the overall TPACK result with the adequacy of ICT tools.

The teachers demonstrate expert knowledge in all TPACK domains. They demonstrate the highest level of knowledge based on the mean of TK (4.28), followed by CK (4.26). While all areas of TPACK have a mean of 4.10, PCK and TPK have the lowest mean (4.11).
