Advantages and Limitations of Sat

Advantages	Limitations
Provides a common metric for comparing applicants from different schools, grading scales, and educational systems.	Heavily coachable, giving students from wealthy families an unfair advantage via expensive test preparation courses and private tutors.
Predicts first-year college grades reasonably well, especially when combined with high school GPA and academic rigor.	Creates significant test anxiety and stress, which can depress performance and misrepresent a student's true academic ability.
Offers a national benchmark that lets students gauge their academic standing against peers across the entire country.	Fails to measure creativity, motivation, or non-cognitive skills that are critical for long-term college and career success.
Allows students to retake the test, and most colleges superscore, which combines the best section scores across attempts.	Disadvantages first-generation and minority students who lack access to prep resources, widening existing achievement gaps.
Provides a uniform, objective scoring system that removes variability from teacher grading and school-specific coursework.	Tests speed and test-taking strategy more than genuine depth of knowledge, rewarding quick guessing over careful reasoning.
Widely accepted by thousands of colleges, making it a single test that covers a broad range of institutions.	Requires significant preparation time, often months of study, that could be spent on coursework, extracurriculars, or work experience.
Offers fee waivers for low-income students, covering registration, extra score reports, and college application fees.	Predicts only first-year grades, not graduation rates or career outcomes, so its long-term validity is questionable.
Includes an optional essay, allowing students to showcase analytical writing skills for colleges that still require it.	Essay section is increasingly irrelevant as most colleges have dropped the requirement, making it a wasted effort for many.
Provides detailed score reports that break down performance by skill, helping students identify weak areas for targeted study.	Score reports are delayed and often arrive after college application deadlines, limiting their usefulness for last-minute decisions.
