What Each Test-Score Line Is Worth at LSU

The cliff math: marginal annual aid value of crossing each ACT, SAT, and GPA threshold. Run this before deciding whether another retake is worth the prep money.

Why this page exists

LSU's automatic merit ladder has measurable cliffs between ACT 24-25 → 26-27 (Tiger Legacy) and ACT 24-25 → 28+ (Tiger Legacy, full range). The marginal dollar value of one extra ACT point isn't linear. It concentrates around the published thresholds, which is why a strategic retake is sometimes worth more than test-optional positioning. The table below is the actual marginal-value math, not generic retake advice.

The only computable cliffs at LSU

Every step below is an arithmetic delta between two published Louisiana Tiger Legacy sub-tiers. The full-COA awards (Stamps, President's Alumni Scholars) have no published stat thresholds, so no cliff can be computed for them.

Threshold	Marginal value	What it means
ACT 24-25 → 26-27 (Tiger Legacy)	+$250/yr ($750 − $500)	A 1.5x step. Real but trivial against a $36,844 in-state COA.
ACT 26-27 → 28+ (Tiger Legacy)	+$250/yr ($1,000 − $750)	Top automatic step, roughly a 1.33x bump.
ACT 24-25 → 28+ (Tiger Legacy, full range)	+$500/yr ($1,000 − $500)	Doubling across the whole automatic ladder, but still only $1,000/yr at the top.

What LSU actually pays by profile

Only the Louisiana Tiger Legacy tier ties dollars to stats. The two full-COA awards are competitive and holistic, with no published stat thresholds.

Profile	Outcome	Notes
In-state · ACT 24-25 (Tiger Legacy)	Louisiana Tiger Legacy — $500/yr	Entry rung of the only stat-automatic award. Requires 3.0 GPA + 24 credits to renew.
In-state · ACT 26-27 (Tiger Legacy)	Louisiana Tiger Legacy — $750/yr	Middle sub-tier. +$250/yr over the 24-25 rung.
Any · ACT 28+ (Tiger Legacy)	Louisiana Tiger Legacy — $1,000/yr	Top automatic rung, still modest. At Alabama a 28+ earns far more; here it caps at $1,000/yr.
Competitive · ~3.5 GPA / 30 ACT (Ogden Honors)	Stamps Scholarship — full cost of attendance	Not automatic. Holistic, Ogden Honors gateway, December 15 priority deadline. Recommended profile 3.5 GPA, 30 ACT.
Competitive · Ogden Honors holistic review	President's Alumni Scholars — full cost of attendance	Second full-COA award, same holistic process and December 15 deadline.

Rules that bite at LSU

The cliff-aware trip wires we'd flag in a custom playbook for LSU.

cliffOne ACT point can move the award by +$250/yr ($750 − $500)
LSU publishes a tier ladder where crossing ACT 24-25 → 26-27 (Tiger Legacy) changes the marginal value by +$250/yr ($750 − $500). A 1.5x step. Real but trivial against a $36,844 in-state COA.
capHard $56,122 cost-of-attendance ceiling
Institutional aid at LSU cannot push the package past $56,122. Big outside wins can mathematically reduce institutional grant once the ceiling is reached.
