**Dataset: Math Achievement, Attitudes, and Anxiety**(Uploaded on )

Mathematics achievement, attitudes, and anxiety were longitudinally assessed for 342 (169 boys) adolescents from 7th to 9th grade, inclusive, and Latent Growth Curve Models were used to assess the relations among these traits and developmental change in them.
