An ongoing assessment is thought to be better than a punctual implementation evaluation, nevertheless a documentary analysis and triangulation of data helped track the implementation process over time.
To mitigate these threats, our methods were tailored to use multiple triangulation of data sources.
To promote credibility, triangulation of data sources and investigator triangulation were used.
Rigor was ensured through independent coding and triangulation of data.
Analysis involved triangulation of data collected by various methods.
Combining these methods facilitated triangulation of data (Denzin 1989).
Methodology: The methodology combined quantitative and qualitative approaches to allow for triangulation of data and sources.
In addition, triangulation of data sources (parents, professionals, experts and literature) and triangulation of researchers will ensure better correspondence between the results and field data.
Triangulation of data enables us to assess the validity of qualitative data.
Due to this triangulation of data sources, not all data sets refer to the same years.
