The laboratory self-sufficiency scale (LÖYÖ) is made of 15 liquid-type substances as a draft. The examples of the study are made by 248 students studying in the classroom teaching and science knowledge teaching program. The technique of orthogonal reversion (varimax) and the principal axis factoring method have been used for the analysis of the opening factor. The factor’s own values are controlled by parallel analysis and determined by the number of factors. Materials that do not serve the purpose of the measurement have been removed from the scale and the factor analysis has been repeated to the person who serves the purpose of all the scale substances. The Cronbach's alpha reliability value of the Cronbach's alpha, which consists of 10 substances and a two-factor structure, is .898 . The first factor was named "Laboratory Positive Skills Perception" and Cronbach's alpha reliability value is .916. The second factor is called "Laboratory Negative Skills Perception" and Cronbach's alpha reliability value is .711.
