Accountability policies through standardized testing are widespread in diverse educational systems. Based on an ethnographic research study, we sought to understand how a learning assessment policy, used for over three decades in primary and lower secondary education, is lived and interpreted in daily school life in Chile. This article analyzes how learning assessment policies are re-contextualized (translated and interpreted) in three elementary and high schools located in poor neighborhoods with different performance categorization according to students' test results. We conducted interviews and observations with teachers and school leadership team members. Results show that school actors experience the effects of testing both as a menace and as a pressure despite their different school categorization performance. They consider the tests a decontextualized and unjust measurement and therefore respond with similar strategies that seek to avoid these negative consequences. This study contributes to understanding the effects of tight accountability systems that attempt to place different levels of pressure through categorization.
