ITI/NCVT Sewing Technology (AITT Theory) study plan

Classify the five stitch classes (100, 200, 300, 400, 500) and sketch one industrial example of each

Draw and label the seam types (superimposed, lapped, bound, flat, edge-finished) with their ISO 4916 style codes

Identify the main parts of a single-needle lockstitch machine and state the function of needle, bobbin case, feed dog, and tension discs

Demonstrate correct needle selection by matching needle size and point type to three given fabric weights

List the daily, weekly, and monthly maintenance checks for a lockstitch machine

Sew and submit samples of at least six seam types with correct seam allowance and neatened edges

Adjust upper and lower thread tension to eliminate puckering and looping, and record the settings used

Calculate fabric consumption for a given garment using marker length and fabric width

Explain grainline, selvedge, bias, and nap, and mark them correctly on a paper pattern

Demonstrate fabric spreading and cutting sequence for a 10-layer lay

Take a set of body measurements on a partner and record them on a standard measurement chart

Draft a basic bodice and sleeve block to the recorded measurements

Identify natural and man-made fibres by burn test and describe the observed flame, odour, and residue

Distinguish warp from weft and explain plain, twill, and satin weave construction with a simple yarn interlacing sketch

Explain fabric shrinkage, grain distortion, and how they affect cutting accuracy

Construct three placket types (two-piece shirt, continuous, and zip fly) and compare their construction steps

Attach a collar with a stand, a patch pocket, and a set-in sleeve on practice fabric

Diagnose and correct five common machine faults such as skipped stitches, needle breakage, and thread breakage

Time each component operation and record the standard minute value for each

Explain the purpose of a feed-off-the-arm and overlock machine in garment assembly

Break a shirt or trouser into its operation sequence and draw a simple operation bulletin

Calculate SAM, efficiency, and hourly production target from given cycle times

Perform a method study on one operation and propose an improved motion sequence

Apply a four-point fabric inspection system to a sample piece and compute the points per 100 square yards

Classify ten common garment defects by cause (material, machine, operator, method) and state the corrective action

Prepare an AQL sampling plan for a given lot size and inspection level and state accept/reject criteria

Identify pressing equipment (steam iron, vacuum table, tunnel finisher) and the correct temperature and pressure setting for three fibre types

Demonstrate pressing of a collar, placket, and dart without shine or distortion

Explain fusing parameters (temperature, pressure, time) and test a fusible interlining bond

Describe packaging, folding, and labelling requirements for export shipment

Identify machine guarding, needle guard, and puller safety devices and list the lockout procedure before needle change

List the ergonomic risk factors in a sewing workstation and propose three corrective measures

Explain the fire triangle, classes of fire, and the correct extinguisher for an electrical fire

Prepare a cost sheet for a garment including fabric, trims, labour, overhead, and profit margin

Draft a short business proposal for a small stitching unit with startup cost estimate

Practice workplace communication: write a work order, a defect report, and a customer complaint reply

Revise all ten domains using timed practice sets and record the score for each domain

Re-attempt every previously missed question and write the correct reasoning for each

Complete two full-length mock tests under exam timing conditions

Compile a one-page formula sheet covering SAM, efficiency, fabric consumption, and costing
