The numbers of education in Portugal are poor, according to the data referenced in the article. The OECD is mentioned as a comparative reference, suggesting that Portugal's results are analyzed in the international context.
The article acknowledges that results may be negative across the entire Organisation for Economic Co-operation and Development, but questions this possibility by stating that this is not necessarily true.
The central point of the text is that this international comparison cannot serve as a justification for the significant degradation that education in Portugal has suffered. This deterioration is evidenced by the presented results.
The title "Lost Decade" suggests that this period represents a time when Portuguese education did not progress or even regressed, with visible consequences in the analyzed data.
