IDEAL problem solver is one of mathematics problem-solving strategies, which function to investigate and describe student's way of thinking in solving problems process. This research aims to analyze mathematical problem-solving skills using modification IDEAL problem solver. This research aimed to explore, categorize, and analyze student's problemsolving skills about word problem of the linear program, which can be used as a basis to consider the improvement of learning. This research is a descriptive study including fifteen senior high school students in Grobogan as its subjects. The research variables are indicators of IDEAL problem solver that students performed including identify problems, define the problem, explore solution, act on the strategies, and look back and evaluate. The data were taken in a form of test and interview. The results showed that the indicator identifying the problems are categorized as very poor (8%), indicator defining the problem is categorized as very poor (8%), indicator exploring the solution is categorized as poor (49%), indicator acting on the strategies is categorized as enough (67%) and indicator looking back and learning is categorized as very poor (31%). Most students were not able to identify the problem and define the goal that resulted to lead the interpretation result.
