Level of education is understood as one of the relevant factors that indicate the development of a society. In Brazil, recent results have pointed out the success of the public education system of the city of Sobral in the state of Ceará, which, in 2017, had the best performance in the country. Given that, it seems relevant to investigate such educational strategies. I analyzed the public education system of Sobral using metacontingency and cultural design as units of analysis. I consulted the city’s educational legislation that was created between January 2001 and May 2020, totaling 12 laws. As a result, I found two metacontingencies, one related to the reformulation of the educational reality of the city and the other regarding the current public education system. In this respect, the actions of several individuals and entities (interlocking contingencies) resulted in the functioning of the public network and the consequent performance of the students (aggregate products), as shown by periodical teaching evaluations (cultural consequence). Additionally, I identified the rearrangement of environmental conditions (both antecedent and subsequent) for the promotion of the cultural practices responsible for the city’s public education system and the consequent long-term results obtained in the educational field. Such deliberate interventions consisted of adequate cultural design. I hope that the conducted analysis and discussions may encourage professionals in public policy to investigate and design effective educational strategies, which in turn may impact the quality of life and the development of society.

受教育程度被理解为指示社会发展的相关因素之一。在巴西，最近的结果表明，塞阿拉州的Sobral市公共教育系统取得了成功，该系统在2017年在该国表现最好。鉴于此，研究这种教育策略似乎很重要。我以元变迁和文化设计为分析单位，对Sobral的公共教育系统进行了分析。我查阅了2001年1月至2020年5月间制定的该市的教育法规，总共有12部法律。结果，我发现了两种元突发事件，一种与重新定义城市的教育现实有关，另一种与当前的公共教育体系有关。在这方面，定期教学评估（文化结果）显示，几个个人和实体的行为（相互关联的突发事件）导致了公共网络的运行，并因此导致了学生的表现（综合产品）。此外，我确定了环境条件的重新安排（包括以前和之后的情况），以促进负责城市公共教育系统的文化习俗以及由此在教育领域获得的长期成果。此类故意干预包括适当的文化设计。我希望进行的分析和讨论可以鼓励公共政策领域的专业人员研究和设计有效的教育策略，进而可能影响生活质量和社会发展。
