Skill Level Instruction Program™ reference chart
Instructors choose the description that best describes the student's performance of each skill. SLIP is for use with Driving Evals only.

|Anticipates problems ahead. Mentally keeps track of other cars in close proximity.
|Keenly aware of potential or hypothetical dangers. Never surprised by cars in mirror or at side.
|A racer’s vision and instinct to anticipate problems before they occur.
|Knows & drives the line
|May not know the track at all or know where to position car for corner entry.
|Drives a basic safe line, but inconsistent and imprecise without continuous instruction.
|Solid, basic line. Understands early / late apex. Uses all track width. Flustered when off-line.
|Drives school line and experiments with alternatives. Always drives own line. Has driven off-line intentionally, but conservatively.
|Comfortable on traditional lines. Drives off-line substantially below the car’s limit.
|Drives school and alternative lines. Comfortable and fast off-line.
|Enters turns faster and earlier than typical instructor.
|Brakes at proper time & intensity
|Abrupt, too soft, very early. Unintentionally trail-brakes. Brakes when frightened.
|Consistent but conservative.
|Hard, steady, timely. Developing trail-braking.
|Proficient trail-braking. Uses release to control rotation. Optional left-foot braking. May slightly overslow the car. Can brake right to apex if needed.
|Expert trail-braking. Brake release skillfully timed to rotate car without overslowing.
|Later and less than typical instructor, expertly initiating rotation.
|Apexes tightly & consistently
|Wide and inconsistent. No understanding of early / late.
|Generally late, but when early may not realize it. Inconsistent.
|Fairly consistent, but conservative.
|Consistent and tight to benign curbs.
|Consistent and tight even to intimidating curbs.
|Pushes for that last inch, sometimes kisses benign curbs.
|Uses as much curb as the car’s suspension will allow.
|Uses track width
|Crabs in. Fails to track out fully.
|Crabs in when tense. Tracks out, but leaves excess room.
|Does not crab in. Tracks out, but leaves excess room to a wall or berm.
|Initiates turn from very edge of track. Tracks out comfortably, even to walls and berms.
|Positions car precisely at turn-in. Tracks out comfortably. Unconsciously unwinds to prevent scrub.
|Aware of track surface, elevation, and geometry. Consistently throttle steers to very edge of track.
|Skillfully places car anywhere on track without overslowing.
|Corner balance & throttle steering
|N/A. Insufficient speed to require balance.
|Delays throttle to avoid understeer.
|Crude balance with throttle.
|Experimenting with controlling rotation with brake release. Aggressive but not greedy with throttle.
|Balances car proficiently with feet. Feels for grip with hands at peak of slip angle curve.
|Expert at balancing the car with feet and hands throughout turn.
|Applies full throttle earlier than typical instructor.
|Makes smooth up and down shifts (Use N/A for auto/SMG)
|No heel-and-toe. May be rushed or awkward.
|Smooth upshifts. No heel-and-toe but smoothly slips clutch.
|Smooth, unhurried shifts. Attempts heel-and-toe with at least marginal success.
|Quick but not rushed. Solid heel-and-toe.
|Quick. Heel-and-toe with little brake pressure release.
|Extremely fast & smooth. Seamless heel-and-toe. No brake pressure release.
|Second nature and automatic.
|Abrupt and/or tentative.
|Squeezes throttle, but little feel or knowledge of effect on car balance.
|Understands effect on balance. Starting to develop sensitivity.
|Sensitive and controlled but occasionally too greedy.
|Consistently uses throttle to steer. Can use abrupt lift for mid-turn rotation, if needed.
|Analyzes turn for optimal throttle application. Always searching for last few RPM of exit speed.
|Aggressively uses throttle in corners.
|Nervous, jerky, inconsistent. Hands not at 9 & 3.
|Smooth but inconsistent turn-in. Saws a bit at the wheel. May require reminders for hand position.
|Relatively smooth and consistent, but may correct course later than optimal due to lack of foresight. Solid 9 & 3. No shuffling unless appropriate.
|No shuffling unless appropriate. Few unneeded corrections. Quick countersteer if needed
|Precise and refined. Relaxed and sensitive grip.
|Analyzes turn geometry and surface for slight optimizations.
|Master at car control.
|Highly inconsistent. No two laps alike.
|Relatively inconsistent. Mistakes vary in each lap.
|Fairly consistent. Focuses attention on specific corners for improvement.
|Highly consistent when trying. May experiment and push in certain corners
|Capable of stringing together a series of fast consistent laps.
|Capable of pushing hard without sacrificing consistency.
|Full throttle on straights, but may lift early when approaching challenging turns.
|Full throttle to braking zone. Corner speed just starting to exhibit slip angles.
|Able to flow with advanced and instructors cars, perhaps as a slower car.
|Solid instructor pace. Uses good slip angles.
|High instructor pace.
|Exceeds instructor pace.
|Anxious in turns and traffic, otherwise reasonably calm.
|Anxious in heavy traffic.
|Fairly poised and comfortable in heavy traffic at speed. Gives and takes late point-bys.
|Very poised and comfortable in heavy traffic. May be anxious side-by-side in corners or braking zones.
|Very poised and comfortable, even in side-by-side situations.
|Highly alert, poised and comfortable. Keenly focused when required.
|Understanding / self-diagnosis
|Limited. May not know when a corner is entered too fast or turn-in is too early.
|At least crude self-diagnosis (e.g. knows when they are early or too hot).
|Moderate self-analysis. Understands not just what happened, but why (root cause) and knows this before corner is completed.
|Advanced self-analysis. Understands event and considers all possible root causes.
|Highly developed self-analysis. Can develop and test strategies for improvement.
|Highly knowledgeable and perceptive. Routinely challenges assumptions and tests alternatives.
