A 2020 analysis of parliamentary activity revealed 21 lawmakers who did not contribute to debates during the session, including Nakuru Town West MP Samuel Arama and Kapseret MP Oscar Sudi, as noted in a 2019 report on legislative engagement.
The Mzalendo Trust scorecard identified 19 National Assembly members and two Senate representatives who remained silent, with male legislators predominating in the list. Other unnamed lawmakers included Abdi Tepo (Isiolo South), Abdi Shurie (Balambala), and Johnson Naicca (Mumias West), among others.
Top performers recognized in the assessment included Millie Odhiambo (Suba North) and David Sankok (Nominated) in the National Assembly, alongside Ledama Ole Kina (Narok) and Moses Wetangula (Bungoma) in the Senate. Female legislators such as Millie Odhiambo and Ruweida Obo (Lamu) also received praise for their participation.
The annual evaluation, based on Hansard records, aims to strengthen accountability between representatives and constituents. Mzalendo Trust Executive Director Caroline Gaita stated the scorecard reinforces the social contract between MPs and citizens by tracking how delegates exercise authority.
The findings coincided with broader discussions about parliamentary effectiveness, particularly as Kenyan lawmakers rank among the world's highest-paid representatives. The report's release followed increased public scrutiny of legislative productivity amid economic challenges.
