Abstract
Quality control is as relevant to scientific computer codes as to any other software. For complex collisional-radiative (CR) models that are used to calculate plasma population kinetics parameters and spectra, each CR code is expected to be thoroughly tested and verified not only against experimental data but also against fundamental principles governing plasma population kinetics. In this Chapter we describe the advanced methods for validation and verification of CR models that were developed at the series of Non-Local Thermodynamic Equilibrium (Non-LTE) Code Comparison Workshops. In addition, the Monte Carlo approach to analysis of uncertainty propagation in CR is exemplified.

Acknowledgments
The success of the NLTE Workshops is due to enthusiastic support of the participants and their inspiring feedback that was always instrumental in development of new code comparison methods. I am very thankful to all of them. In particular, it is my great pleasure to acknowledge Richard Lee (LLNL), Spiros Alexiou (University of Crete), Christopher Bowen (CEA), James Colgan (LANL), Hyun-Kyung Chung (LLNL/IAEA), Chris Fontes (LANL), Stephanie Hansen (LLNL/SNL), and Jesus Rubiano (University of Las Palmas de Gran Canaria) who had selflessly taken on themselves the duties of case development, session coordination, and general workshop organization. I also thank Evgeny Stambulchik (WIS) and Alexander Kramida (NIST) for valuable comments.
