(interaction of entanglement and effects tests forces schools “to tread an extremely narrow line”); Roemer., 426 U. S., at 768-769 (White, J., concurring in judgment). For this and other reasons, the “entanglement” prong of the Lemon test has been much criticized over the years. See, e. g., Aguilar v. Felton, supra, at 429 (O’Connor, J., dissenting); Wallace v. Jaffree, 472 U. S. 38, 109-110 (1985) (Rehnquist, J., dissenting); Lynch v. Donnelly, 465 U. S., at 689 (O’Connor, J., concurring); Lemon, supra, at 666-668 (White, J., concurring and dissenting). Most of the cases in which the Court has divided over the “entanglement” part of - the Lemon test have involved aid to parochial schools; in Aguilar v. Felton, for example, the Court’s finding of excessive entanglement rested in large part on the undisputed fact that the elementary and secondary schools receiving aid were “pervasively sectarian” and had “‘as a substantial purpose the inculcation of religious values.’” 473 U. S., at 411 (quoting Nyquist, 413 U. S., at 768); see also 473 U. S., at 411 (expressly distinguishing Roemer, Hunt, and Tilton as cases involving aid to institutions that were not pervasively sectarian). In Aguilar, the Court feared that an adequate level of supervision would require extensive and permanent on-site monitoring, 473 U. S., at 412-413, and would threaten both the “freedom of religious belief of those who [were] not adherents of that denomination” and the “freedom of . . . the adherents of the denomination.” Id., at 409-410.
Here, by contrast, there is no reason to assume that the religious organizations which may receive grants are “pervasively sectarian” in the same sense as the Court has held parochial schools to be. There is accordingly no reason to fear that the less intensive monitoring involved here will cause the Government to intrude unduly in the day-to-day operation of the religiously affiliated AFLA grantees. Unquestionably, the Secretary will review the programs set up and run by the AFLA grantees, and undoubtedly this will involve a review of, for example, the educational materials that a
