The right of admission to private elementary schools can no longer be exercised arbitrarily in Mexico. This was established by the First Chamber of the Supreme Court of Justice of the Nation through Jurisprudential Theses 1a./J. 15/2024 and 1a./J. 17/2024. Both rulings stem from Amparo Appeal 57/2022, decided on January 25, 2023, under the opinion of Justice Jorge Mario Pardo Rebolledo. Therefore, no private elementary school can openly and arbitrarily reserve the right to admit or reject students. Consequently, parents and educational institutions must be aware of the true scope of this ruling.
What Does the Thesis Say About the Right of Admission in Private Schools?
The First Chamber determined that no private educational institution at the basic education level may adopt normative, advertising, contractual, or de facto positions. Such positions cannot openly reserve the right of admission to students. On the contrary, access to these institutions must be granted under conditions of equal opportunity and non-discrimination. Furthermore, the Court specified that the social repercussions of a reserved admission policy affect the right to education, protected by Article Three of the Constitution. It also affects the best interests of the child, protected by Article Four.
According to Guillermo Pablo López Andrade, Of Counsel at Baráibar & Asociados, the Court recognized something many families had suspected for years. “The prestige of a school cannot translate into the right to freely discriminate between whom it admits and whom it does not,” the specialist points out. This reflection summarizes the spirit of the ruling, which aims to balance the contractual freedom of schools with the fundamental rights of children and adolescents.
Background of the Litigation that Gave Rise to the Criterion
The case reached the Supreme Court through an appeal for review, filed against the denial of enrollment for a family at a private school. During the litigation, it was argued that the school had exercised its right of admission without further justification. However, the First Chamber considered this argument insufficient in light of the constitutional rights at stake. For this reason, the analysis focused on the General Law of Education and the obligations it imposes on private entities.
This law establishes the duty of private educational institutions to avoid compromising equal treatment of students. It also empowers the federal education authority to issue regulations governing school administration in basic education. These regulations must facilitate enrollment, re-enrollment, accreditation, promotion, regularization, and certification of studies. Therefore, the Court concluded that reserving the right of admission without objective and verifiable criteria violates this legal framework.

Constitutional Basis of the Right of Admission to Private Schools
Article Three: The Right to Education
Article Three of the Constitution recognizes the right of every person to receive an education. Therefore, any practice that hinders access to this right, even if carried out by private entities, is subject to constitutional review. In this regard, the Court emphasized that basic education is of a public interest that transcends the contractual relationship between the school and the family.
Article Four: The Best Interests of the Child
Article Four of the Constitution, for its part, mandates that all decisions concerning children and adolescents must consider their best interests. Likewise, the General Law on the Rights of Children and Adolescents requires adults to adopt measures that promote and protect these rights. This obligation extends to private institutions. Consequently, a refusal of admission without objective justification violates this constitutional standard.
Background: The Debate on Discrimination in Access to Private Services
This criterion did not arise in isolation. Over the past decade, various courts have analyzed whether private entities, when providing services, can arbitrarily deny access. The Federal Law to Prevent and Eliminate Discrimination has long recognized that denying a service for discriminatory reasons constitutes a legal violation. These reasons include ethnic origin and social status, among other protected categories. However, in the case of basic education, the Court added an additional element: the best interests of the child. This element strengthens protection against arbitrary decisions.
Therefore, this criterion aligns with a growing body of case law that expands constitutional oversight of the actions of private entities. This oversight applies when they provide services of public interest, such as education, healthcare, or transportation. Consequently, private schools cease to operate under a purely contractual framework and become subject to the same standards of equality as public institutions.
What can other service sectors learn from this criterion?
Although the thesis specifically addresses basic education, its reasoning is useful for other sectors that serve the general public. Sports clubs, daycare centers, private clinics, and membership platforms face similar questions about the limits of their contractual freedom in relation to the rights of their users. For example, denying access to a service without objective and documented criteria can generate liability, even outside the educational sphere, when fundamental rights are at stake.
In fact, the Federal Law to Prevent and Eliminate Discrimination already includes sanctions for service providers who deny access for discriminatory reasons. However, this ruling by the First Chamber strengthens that protection by directly linking it to the best interests of the child, thus raising the bar for any institution that serves minors, beyond the strictly educational sector.
How does this criterion affect you if you are trying to register a minor?
If your family applies to enroll a child in a private elementary school, the institution can no longer deny admission without objectively explaining the reasons. For example, it is not enough to invoke a generic "right of admission reserved" clause in the contract or in the school's advertising. Instead, the school must demonstrate reasonable, verifiable, and non-discriminatory criteria, such as available space or academic requirements clearly communicated in advance.
Likewise, if you believe your family was arbitrarily rejected, you can pursue legal action to demand respect for this legal precedent. Similarly, local and federal education authorities have oversight mechanisms for the school regulations that private institutions must follow. Additionally, the National Council to Prevent Discrimination can receive complaints when a denial of admission masks unequal treatment based on categories protected by law.

What clauses should schools avoid in contracts and advertising?
Many private schools still include clauses such as “the institution reserves the right of admission” in their enrollment contracts or in their print and digital advertising. These types of clauses, drafted generically and without objective criteria, directly contravene the ruling of the First Chamber. For example, denying admission to a minor based on their appearance, perceived socioeconomic status, or family structure, without documentary evidence, constitutes an arbitrary refusal of admission.
However, clauses establishing quota limits per group, academic requirements applicable equally to all applicants, or objective and transparent psycho-pedagogical evaluation processes are valid. Therefore, the central difference lies in the objectivity and uniform application of the criteria, not in the very existence of a selection process.
Documents that a School Must Keep to Accredit Objective Criteria
An educational institution wishing to avoid legal issues must maintain documentary evidence of its admissions processes. Each applicant's file should include the application form, the results of any administered assessments, and all communications sent to the family. The criteria for available spaces per group must also be recorded, along with the date of the last update and the person responsible for defining them.
Schools with psychoeducational assessment processes need clear protocols outlining what each instrument measures and how the results are interpreted. An instrument administered without a transparent methodology can be interpreted as a hidden barrier to admission, particularly if its results disproportionately exclude certain groups of applicants. School principals should receive regular training on these standards, given that admission decisions are often made at the school level, without direct legal oversight.
Institutional advertising deserves special attention. School brochures, websites, and social media should not suggest, even implicitly, that certain types of families are welcome and others are not. Regularly reviewing these materials, with legal counsel, significantly reduces the risk of a complaint or lawsuit succeeding. Maintaining evidence of this review also constitutes valuable documentary evidence against any future claims.
Implications for Private Educational Institutions
Private elementary schools should review their internal regulations, enrollment contracts, and advertising materials to eliminate any clauses that reserve the right to admit students in an open or arbitrary manner. Furthermore, they should document objective selection criteria, where they exist, such as enrollment limits or academic requirements that apply equally to all applicants.
According to Guillermo Pablo López Andrade, “educational institutions that operate transparently in their admissions processes not only comply with the law, but also strengthen families' trust in their school community.” Therefore, rather than a limitation, this criterion represents an opportunity to professionalize the admissions process.
Differences between Basic Education and Other Educational Levels
It is worth clarifying that this thesis focuses specifically on basic education, given the paramount importance of children's well-being. In contrast, upper secondary and higher education levels could allow for greater discretion, provided that objective and non-discriminatory academic criteria exist, such as standardized entrance exams or minimum grade point averages. Nevertheless, the general principle of equality of opportunity remains a relevant reference point for any educational level.
Furthermore, private universities retain greater autonomy in designing their selection processes, by virtue of their constitutionally recognized academic freedom. However, even within this context, discrimination based on factors other than academic merit remains prohibited under the Federal Law to Prevent and Eliminate Discrimination. Therefore, all educational institutions, regardless of their level, must avoid practices that exclude applicants based on subjective or discriminatory criteria.
High schools, for example, typically administer standardized entrance exams with publicly available rules and predetermined minimum scores. This type of mechanism, in principle, meets the standard of objectivity required by jurisprudence. Universities, on the other hand, document their selection processes through public calls for applications, which makes it easier to demonstrate the absence of arbitrariness in any subsequent review.
Practical Recommendations for Families and Institutions
First, families should request in writing the reasons for any enrollment rejection. Then, they should keep all advertising materials, contracts, and communications related to the admissions process. For their part, educational institutions should train their administrative staff on this criterion so that enrollment processes comply with the standards set by the Court.
Similarly, it is advisable that schools update their enrollment contracts with the support of specialized legal counsel, replacing generic clauses with objective and verifiable criteria. Finally, both families and schools can benefit from preventative legal advice, which anticipates conflicts and reduces the risk of unnecessary litigation.

Conclusion
With these principles, the right of admission to private schools has found a clear limit against arbitrariness. Based on this criterion, no institution at the basic education level can reject applications without objectively justifying its reasons. On the contrary, equal opportunities and non-discrimination become the mandatory standard for any enrollment process. Families thus gain a solid legal tool against arbitrary decisions. Meanwhile, educational institutions must adapt their processes to avoid legal contingencies and strengthen the trust of the school community.

Private elementary schools can no longer simply reserve the right of admission. The First Chamber of the Supreme Court of Justice of the Nation (SCJN) established this through rulings 1a./J. 15/2024 and 1a./J. 17/2024, stemming from a case resolved in 2023. This ruling mandates that access to private elementary education be based on equality and non-discrimination. According to Guillermo Pablo López Andrade, Of Counsel at our firm, “a school’s prestige cannot translate into the right to freely discriminate against whom it admits.” For institutions, this means reviewing regulations, contracts, and advertising. For families, it represents a concrete legal tool against arbitrary rejections. Has your institution already adapted its admissions processes to this standard?
