This study aimed to develop a valid and reliable scale that reveals secondary school pupils' attitudes toward science literacy. The survey model, one of the quantitative research methods, was used in the study. The validity and reliability study of the scale was carried out on secondary school pupils attending public schools in Turkey in the 2022-2023 academic year. Data were collected from 546 secondary school pupils. The structure of the draft scale, established through Exploratory Factor Analysis (EFA), consisted of 16 items and 4 dimensions. The scale was administered to 392 secondary school pupils to verify the structure revealed by EFA. This validated a 16-item and 4- dimension structure. The total variance explained by the scale was 50.11%. The Cronbach alpha coefficient, which indicates the scale's internal consistency, was calculated to be 0.867. Fit indexes were calculated as X2/df =2.38, NFI= 0.92, NNFI= 0.94, RFI= 0.90, CFI= 0.95, GFI= 0.93, AGFI= 0.90, SRMR= 0.055, IFI= 0.95 and RMSEA= 0.060. In conclusion, it can be said that the "Attitude Towards Science Literacy Scale" is qualified to measure the attitude of secondary school pupils towards science literacy.
