Background: The Ireland North and South Report Card on Physical Activity (PA) for Children and Adolescents aims to monitor progress in PA participation across a range of internationally established indicators. Methods: Data were collated for 11 indicators and graded following the harmonised Active Healthy Kids Global Alliance report card process. Six representative studies (sample size range n = 898 to n = 15,557) were primarily used in the grading, with many indicators supplemented with additional studies and reports. Data collected since the implementation of COVID-19 public health measures in March 2020 were excluded. Results: Grades were awarded as follows: `Overall physical activity¿, C-; `Organised Sport and Physical Activity¿, C; `Active Play¿, INC; `Sedentary Behaviours¿, C-; `Physical Fitness¿, INC; `Family and Peers¿, D+; `School¿, C-; `Physical Education¿, D; `Community and Environment¿, B+ and `Government¿, B. Separate grades were awarded for disability as follows; `Overall physical activity¿, F; `Organised Sport and Physical Activity¿, D; `Sedentary Behaviours¿, C-; `Family and Peers¿, C; `School¿, C- and `Government¿, B. `Active Play¿, `Physical Fitness¿, `Physical Education¿ and `Community and Environment¿ were all graded INC for disability. Since the last report card in 2016, four grades remained the same, three increased (`Overall physical activity¿, `School¿ and `Physical Education¿) and two (`Family and Peers,¿ and `Government¿) were awarded grades for the first time. Conclusion: Grades specific to children and adolescents with disability were generally lower for each indicator. While small improvements have been shown across a few indicators, PA levels remain low across many indicators for children and adolescents.
