It's impossible to know Albert Einstein's precise IQ score.
While often cited as being around 160, this is just an estimate. Einstein never took a standardized IQ test as an adult. The rumored IQ of 160 is based on retrospective analysis and comparison to the IQ scores of other individuals with similar intellectual achievements.
Therefore, any specific number given for Einstein's IQ is purely speculative and should be treated as an approximation, not a definitive measurement.
